Abstract:
Optimal operation and control of heat recovery in an integrated Laboratory Air Handling Unit (LAHU) system differs substantially from that in conventional dedicated AHUs for laboratory buildings with a 100% outside air AHU for laboratory spaces, since the LAHU allows economizer operation for both offices and laboratories. Optimal operation and control schedules of the heat recovery systems in the LAHU have been developed to minimize the total thermal energy cost. This paper presents the procedure, methodology, and results of generic optimal heat recovery control schedules for the LAHU and investigates its impact on the LAHU potential thermal and pump energy savings. The optimal control schedule can potentially save 14% to 27% thermal energy and 17% to 100% pump energy during the winter under weather conditions that prevail in Omaha, Nebraska. The findings discussed in this paper also apply to any heat recovery system, where AHU has an economizer function.

Abstract:
Retrofit or replacement of few units in a subcritical facility may not only improve overall efficiency of conversion of energy in a power plant but also support sustainability issues. The primary objective of this article is to identify model parameters of a coal-fired integrated boiler and to present a comparative study on three different identification methods. This leads to select most suitable models that are applied for the developed model of the boiler of 210 MW coal-fired thermal power plants. The mathematical models of economizer, drum, and super-heater assembly are derived using mass balance and energy balance equations. The derived multi input–multi output model is then validated, and the model parameters are identified using three different identification methods namely nonlinear least square technique, maximum likelihood estimation, and expectation maximization algorithms. Identification of the plant model will essentially help to frame a good controller. In this article, parameter estimation has been carried out from real-time plant as it provides selective tool through quantitative comparative study of the three methods. The expectation maximization method has been found to provide suitable results compared to the other two methods. Model parameters of integrated boiler of a comprehensive structure have been obtained for the first time using expectation maximization method.

Abstract:
Abstract Steam generators are one of the most important components of pressurized-water reactors. This component plays the role of heat transfer and pressure boundary between primary and secondary side fluids. The Once Through Steam Generator (OTSG) is an essential component of the integrated nuclear power system. In this paper, steady-state analysis of primary and secondary fluids in the Integral Economizer Once Through Steam Generator (IEOTSG) have been presented by Single Heated Channel (SHC) and subchannel modelling. Models have been programmed by MATLAB and FORTRAN. First, SHC model has been used for this purpose (changes are considered only in the axial direction in this model). Second, the subchannel approach that considers changes in the axial and also radial directions has been applied. Results have been compared with Babcock and Wilcox (B&W) 19- tube once through steam generator experimental data. Thermal- hydraulic profiles have been presented for steam generator using both of models. Accuracy and simplicity of SHC model and importance of localization of thermal-hydraulic profiles in subchannel approach have been proved.

Abstract:
The article describes the main tasks that need to be solved when automating technological processes at TPS. Technological processes at TPS take place in difficult conditions, which complicates the management tasks. When creating an automated control system, modern software and technical complexes are used, which are developed by domestic manufacturers. The software and hardware complex allows you to solve all the problems of monitoring and controlling technological processes in all operating modes of power equipment. They can be used for both newly constructed and reconstructed energy facilities. The basis of the Software and hardware complex is programmable logic controllers that support medium and distributed automation. The article discusses some Russian-made controllers. Since 2019, the automated control system of the boiler-economizer is being designed by NVT-Systems at the Dzerzhinsk TPS. The implemented Software and hardware complex needs to be integrated into the existing automation structure, in addition, simplicity, reliability and redundancy are required. For these reasons, the REGUL500 controller was selected. The controller is characterized by very high performance, reliability, and the ability to work in distributed systems in real time. In addition, the advantages of the REGUL500 controllers are: high accuracy of the measuring channels; the possibility of hot-swapping modules of all types; resistance to external influences. The REGUL controller has a set of various Russian certificates of conformity.

Abstract:
Closed supercritical carbon dioxide (S-CO2) Brayton cycle is a promising alternative to steam Rankine cycle due to higher cycle efficiency at equivalent turbine inlet conditions, which has been explored to apply to nuclear, solar power, waste heat recovery, and coal-fired power plant. This study establishes 300MW S-CO2 power system based on modified recompression Brayton cycle integrated with coal-fired circulating fluidized bed (CFB) boiler. The influences of two stages split flow on system performance have been investigated in detail. In addition, thermodynamic analysis of critical operating parameters has been carried out, including terminal temperature difference, turbine inlet pressure/temperature, reheat stages, and parameters as well as compressor inlet pressure/temperature. The results show that rational distribution of split ratio to the recompressor (SR1) achieves maximal cycle efficiency where heat capacities of both sides in the low temperature recuperator (LTR) realize an excellent matching. The optimal SR1 decreases in the approximately linear proportion to high pressure turbine (HPT) inlet pressure due to gradually narrowing specific heat differences in the LTR. Secondary split ratio to the economizer of CFB boiler (SR2) can recover moderate flue gas heat caused by narrow temperature range and improve boiler efficiency. Smaller terminal temperature difference corresponds to higher efficiency and brings about larger cost and pressure drops of the recuperators, which probably decrease efficiency conversely. Single reheat improves cycle efficiency by 1.5% under the condition of 600°C/600°C/25Mpa while efficiency improvement for double reheat is less obvious compared to steam Rankine cycle largely due to much lower pressure ratio. Reheat pressure and main compressor (MC) inlet pressure have corresponding optimal values. HPT and low pressure turbine (LPT) inlet temperature both have positive influences on system performance.

Abstract:
Waste energy represents one of the most critical issues for the economic utilization and management of energy in modern industrial fields. This article outlines a scheme to utilize two different source temperature levels within the envelope of higher than 200 °C zones. Two regenerative organic Rankine cycles (RORC) were implemented to construct a compound regenerative organic Rankine cycle (CRORC) to improve the energy management of the sources. These two mini-cycles were integrated throughout an intermediate economizer circuit to extract a certain amount of energy from the high-temperature level mini-cycle. R-123 was circulated in the high-temperature cycle due to its high critical temperature at evaporation and condensation temperatures of 160 °C and 50 °C, respectively. R-123, R-21, and hydrocarbon R-600 were used as working fluids for the low-temperature cycle at evaporation and condensation temperatures of 130 °C and 35 °C, respectively. The R-123 fluid in the high-temperature mini-cycle was superheated to 170-240 °C, whereas the fluid in the low-temperature level was superheated to 180 °C. The results showed that the independent system (IRORC) requires more energy recovery than the compound system by a maximum of 2% to achieve the same net power output. This corresponds to the enhancement of 2% for the system net thermal efficiency of the compound (CRORC) system compared to the independent (IRORC) one. The compound (CRORC) system revealed a net thermal efficiency in the range of 14% and 15.6% for the test conditions. The mini-cycle net thermal efficiency of the low-temperature in the compound system was enhanced by a range of 2.5-5% compared to that of the independent arrangement. R-123/R-123 and R-123/R-21 systems exhibited higher net thermal efficiencies than the R-123/R-600 one by 3% and 2%, respectively. Increasing the superheat degree of the high-temperature mini-cycle from 10 °C to 80 °C for the compound system has improved the thermal efficiency by 7.6-7.9% for the examined fluid pairs and operating conditions.

Abstract:
Aggregate demand is influenced by the functional income distribution of an economy and that of its trading partners. This relationship between income distribution and output is analyzed in a short-run two-country Neo-Kaleckian model. The effects of devaluation and redistribution are discussed in detail. Trade and redistribution within one country interact and output increases or decreases with changes in either depending on the specific distributional and exchange rate movements. The Marshall-Lerner condition is shown to be equivalent to the assumption of expansionary devaluation. If devaluation increases output, national redistribution policy toward wage earners is also more likely to be expansionary. (author's abstract)

Abstract:
L'explosion de demande de bande passante est une conséquence de l'augmentation du volume de trafic. Il est important de proposer des mécanismes pour transférer le trafic entre les réseaux interconnectés de manière efficace. D'autre part, il est prévu que les réseaux d'accès (optiques et mobiles) constituent les plus grands consommateurs d'énergie dans les réseaux optiques pour les dix prochaines années. Cette situation et l'impact croissant des réseaux sur l'environnement ont fait devenir l'efficacité énergétique dans les réseaux de télécommunications un thème important de recherche. Cette thèse se concentre donc sur la proposition de nouvelles solutions aux problèmes liées à l'augmentation du volume de trafic dans différentes segments des réseaux. Tout d'abord, nous avons étudié différents schèmes de transfert du trafic entre les réseaux interconnectes en utilisant la synchronisation. Puis, nous avons exploré la possibilité d'offrir différents services dans les réseaux intégrés optiques-mobiles. Nous avons présenté une nouvelle architecture pour la conception de l'unité de réseau optique (ONU). Ensuite, nous nous sommes focalisés sur l'économie de l'énergie et des solutions efficaces pour l'allocation de bande passante ont été proposées. Nous avons également proposé un algorithme qui fournit l'efficacité énergétique pour les récepteurs sans fil dans les ONUs hybride. Une analyse des performances en utilisant modèles de files d'attente a été présentée. Finalement, nous avons analysé le trafic hétérogène dans l'ONU hybride, et nous avons proposé un cadre pour un algorithme d'ordonnancement qui puisse mettre à jour les règles de service de façon dynamique
A big growth in the number of subscribers is increasing the traffic volume passing through each sector in a telecommunication network. Mechanisms are required to solve the traffic shift problem between two sectors of the network in an efficient way. Additionally, it is expected that the access networks (optical and wireless) will constitute the largest energy consumers among the networks for the next ten years. This situation and the increasing impact of networks on the environment have made become the energy efficiency in telecommunication networks an important theme for researches. This dissertation hence focuses on the proposition of novel solutions for deal with the problems due to the growing of traffic in different segments of the network. Firstly, we have studied the traffic shift between interconnected networks by using the synchronization as technique to solve this problem. Secondly, we have explored the possibility of provisioning different services over the integration of optical-wireless technologies, which has been considered as a promising candidate for the deployment of high-speed access networks. Architecture of design for the Optical Network Unit (ONU) is presented. Then, energy efficiency has been focused and effective bandwidth management solutions have been proposed. We have also proposed an energy efficiency algorithm for wireless receiver at hybrid ONUS. A performance analysis by queuing models was presented for the implementation of proposed solutions. Finally, we have analyzed the heterogeneous traffic at hybrid ONU, and we have proposed a framework for a scheduling algorithm considering the characteristics of different traffic sources

Abstract:
There is an urgent need for wastewater treatment plants (WWTPs) to adapt to a rise in water and energy demands, prolonged periods of drought, climate variability, and resource scarcity. As population increases, minimizing the carbon and energy footprints of wastewater treatment, while properly managing nutrients is crucial to improving the sustainability WWTPs. Integrated resource recovery can mitigate the environmental impact of wastewater treatment systems; however, the mitigation potential depends on various factors such as treatment technology, resource recovery strategy, and system size. Amidst these challenges, this research seeks to investigate the environmental sustainability of wastewater treatment plants (WWTPs) integrating resource recovery (e.g., water reuse, energy recovery and nutrient recycling) in different contexts (developing versus developed world) and at different scales (household, community, and city). The over-arching hypothesis guiding this research is that: Context and scale impact the environmental sustainability of WWTPs integrated with resource recovery. Three major research tasks were designed to contribute to a greater understanding of the environmental sustainability of resource recovery integrated with wastewater treatment systems. They include a framework development task (Chapter 2), scale assessment task (Chapter 3), and context assessment task (Chapter 4). The framework development task includes a critical review of literature and models used to design a framework to assess the environmental sustainability of wastewater treatment and integrated resource recovery strategies. Most studies used life cycle assessment (LCA) to assess these systems. LCA is a quantitative tool, which estimates the environmental impact of a system over its lifetime. Based on this review, a comprehensive system boundary was selected to assess the life cycle impacts of collection, treatment, and distribution over the construction and operation and maintenance life stages. Additionally, resource recovery offsets associated with water reuse, energy recovery, and nutrient recycling are considered. The framework’s life cycle inventory includes material production and delivery, equipment operation, energy production, sludge disposal, direct greenhouse gas (GHG) emissions, and nutrients discharged to the environment. Process-based LCA is used to evaluate major environmental impact categories, including global impacts (e.g., carbon footprint, embodied energy) and local impacts (e.g., eutrophication potential). This is followed by an interpretation of results using sensitivity or uncertainty analysis. The scale assessment task investigates how scale impacts the environmental sustainability of three wastewater treatment systems integrated with resource recovery in a U.S. context. Household, community, and city scale systems using mechanized technologies applicable to a developed world setting were investigated. The household system was found to have the highest environmental impacts due high electricity usage for treatment and distribution, methane emissions from the septic tank, and high nutrient discharges. Consequently, the life cycle impacts of passive nutrient reduction systems with low energy usage at the household level merit further investigation. The community scale system highlights trade-offs between global impacts (e.g., embodied energy and carbon footprint) and local impacts (e.g., eutrophication potential) where low nutrient pollution can be achieved at the cost of a high embodied energy and carbon footprint. The city scale system had the lowest global impacts due to economies of scale and the benefits of integrating all three forms of resource recovery: Energy recovery, water reuse, and nutrient recycling. Integrating these three strategies at the city scale led to a 49% energy offset, which mitigates the carbon footprint associated with water reuse. The context assessment task investigates how context impacts the environmental sustainability of selected community scale systems in both Bolivia and the United States. In this task, rural developing world and urban developed world wastewater management solutions with resource recovery strategies are compared. Less mechanized treatment technologies used in rural Bolivia were found to have a lower carbon footprint and embodied energy than highly mechanized technologies used in urban United States. However, the U.S. community system had a lower eutrophication potential than the Bolivia systems, highlighting trade-offs between global and local impacts. Furthermore, collection and direct methane emissions had more important energy and carbon implications in Bolivia, whereas treatment electricity was dominant for the U.S. community system. Water reuse offsets of embodied energy and carbon footprint were higher for the U.S community system, because high quality potable water is replaced instead of river water. In contrast, water reuse offsets of eutrophication potential were high for the Bolivia systems, highlighting the importance of matching treatment level to end-use application. One of the Bolivia systems benefits from the integration of water, energy, and nutrient recovery leading to beneficial offsets of both global and local impacts. This research can potentially lead to transformative thinking on the appropriate scale of WWTPs with integrated resource recovery, while highlighting that context lead to changes in the dominant contributors to environmental impact, appropriate technologies, and mitigation strategies.

Abstract:
O monocultivo, delineamento da produção agropecuária mais tradicional, desde a Revolução Verde, têm sido relacionado ao desequilíbrio ambiental de ecossistemas, e escassez de recursos naturais. Neste contexto, sistemas integração lavoura-pecuária (ILP) tem se mostrado promissores em relação à benefícios ambientais e produtivos, quando comparada a sistemas de monocultivo. Existe, todavia, poucos trabalhos que abordam os benefícios econômicos potenciais dos sistemas ILP. O objetivo desta dissertação foi desenvolver análise econômica e financeira da produção de milho grão e bovinos de corte em sistemas de monocultivo e ILP. A primeira etapa para o desenvolvimento da pesquisa foi a coleta de dados do projeto intitulado Impacto ambiental, produtividade e viabilidade econômica de sistemas de monocultivo e integrado de lavoura pecuária, financiado pela Fapesp (Processo Nº 2014/24514-6) delineado a partir de seis tratamentos experimentais: T1) Monocultivo de milho grão; T2) Monocultivo Brachiaria brizantha cv. Marandu; T3) Integração entre milho e Brachiaria brizantha cv. Marandu, semeados simultaneamente; T4) Integração entre milho e Brachiaria brizantha cv. Marandu, semeados simultaneamente, com aplicação de herbicida; T5) Integração entre milho e Brachiaria brizantha cv. Marandu, tendo sido o capim semeado na adubação de cobertura do milho; T6) Integração entre milho e Brachiaria brizantha cv. Marandu, semeados simultaneamente, na linha e entrelinha do milho, com aplicação de herbicida. A segunda etapa foi a cálculo dos custos variáveis dos tratamentos experimentais. A terceira etapa consistiu no cálculo do custo total de produção de sistemas de produção representativos comerciais, que replicassem os manejos e tecnologias utilizados nos tratamentos experimentais. A quarta etapa consistiu na análise financeira, tendo sido o valor presente líquido (VPL), a taxa interna de retorno (TIR) e o PayBack os indicadores de tomada de decisão. O software Microsoft Excel® foi utilizado para o cálculo dos custos de produção, construção do fluxos de caixa e estimativa dos indicadores de viabilidade. Os resultados indicaram ganhos econômicos da ILP, em relação ao monocultivo, explicados pela teoria da economia de escopo. As fontes da economia de escopo identificadas nessa pesquisa foram: diluição de custos fixos e complementariedades técnicas compartilhadas. Os custos de produção unitários da lavoura e da pecuária foram menores na ILP do que nos sistemas de monocultivo. Os sistemas ILP e o monocultivo de milho grão foram considerados economicamente viáveis, com base no VPL, TIR e PayBack. O VPL do sistema ILP foi maior do que do sistema de monocultivo de milho, o que demonstrou outro benefício econômico dos sistemas integrados, se comparados ao monocultivo. A pecuária monocultivo foi economicamente inviável, baseado nos mesmos indicadores de viabilidade econômica.
Monoculture farming, the traditional agriculture approach since the Green Revolution, has been associated with the environmental imbalance of ecosystems and with the scarcity of natural resources. Within this context, integrated crop-livestock (ICL) systems have shown to be promising in terms of environmental and productive benefits when compared to monoculture systems. However, few studies have addressed the potential economic benefits of ICL systems. The objective of this dissertation was to perform an economic and financial analysis of corn grain and beef cattle production in monoculture and ICL systems. The first phase of the study consisted of the collection of data from the project entitled Environmental impact, productivity and economic viability of monoculture and integrated crop-livestock systems, financed by Fapesp (2014/24514-6) and designed in six experimental treatments: T1) corn monoculture; T2) Palisade grass (Brachiaria brizantha cv. Marandu) monoculture; T3) corn plus Palisade Grass sown simultaneously; T4) corn plus Palisade Grass sown simultaneously plus herbicide; T5) Palisade grass sown at topdressing corn; T6) Palisade Grass sown at the line and inter-line of corn. In the second phase, the variable costs of the experimental treatments were calculated. The third phase consisted of calculating the total production cost of representative commercial production systems that replicate the managements and technologies used in the experimental treatments. The fourth phase consisted of financial analysis using the net present value (NPV), internal rate of return (IRR), and payback as indicators for decision making. The Microsoft Office Excel software was used for the calculation of production costs, cash flow definition, and estimation of viability indicators. The results indicated economic gains of the ICL system compared to monoculture, explained by the theory of economies of scope. The sources of economies of scope identified in this study were the dilution of fixed costs and shared technical complementarities (fertilizers for example). The unit production costs of livestock and crop were lower in the ICL than in the monoculture system. The ICL systems and corn grain monoculture were considered economically viable based on NPV, IRR, and PayBack. The NPV of ICL systems was bigger than the NPV of corn grain monoculture, which has shown another economic benefit of the integrated systems compared to monoculture. The livestock monoculture system proved to be economically unviable because of the negative NPV and IRR below the minimum attractive rate considered.

Au cœur de cette thèse réside l'application des méthodes d'optimisation et d'études empiriques pour traiter des questions de développement durable dans le secteur de l'électricité du Vietnam pour les 30 prochaines années. On examine les moyens des options énergétiques durables pour le secteur de l'électricité. La thèse s'organise en deux parties. (i) Dans la première partie, nous développons le modèle " bottom-up " de planification intégrée des ressources (IRP) pour fournir une évaluation plus exhaustive de l'état actuel et des perspectives d'avenir pour le secteur de l'électricité du Vietnam dans les trois prochaines décennies. Puis, en utilisant une analyse comparative et une analyse de la vulnérabilité qui est basée sur la simulation IRP, nous analysons les vulnérabilités auxquelles le développement du secteur devra faire face, en termes de dimensions économiques et socio-environnementales. Nous avons en outre développé le modèle IRP, représentant les coûts marginaux de réduction des émissions de carbone de manière réaliste en tenant compte des valeurs non nulles de carbone et de limitation des émissions de carbone, afin de simuler des options d'approvisionnement énergétique soutenables pour le secteur de l'énergie. (ii) Dans la deuxième partie, nous étudions les principaux obstacles contre une adoption plus large des énergies soutenables à l'aide d'enquêtes formelles parmi les experts nationaux. Ensuite, nous utilisons une approche d'analyse empirique pour examiner les différents outils politiques appropriés, y compris des instruments d'incitation / régimes et la réforme du secteur pour une telle durabilité du secteur de l'énergie. Pour la fin, nous analysons l'accès aux sources de financement possibles pour le développement durable dans le secteur de l'électricité du Vietnam.

Abstract:
Le Grand Sousse, partie orientale du gouvernorat de Sousse, abrite l'une des plus importantes métropoles régionales du pays, avec une concentration sur la frange littorale des activités humaines et économiques. L'explosion démographique et la généralisation de la desserte en eau potable en font un important foyer de consommation d'eau. Or cette région est aussi très marquée par l'aridité, cause principale de faibles ressources locales. Dépendante des régions voisines pour son approvisionnement en eau, le Grand Sousse mène depuis toujours une course au captage pour satisfaire des besoins grandissants. La stratégie politique traditionnelle de mobilisation et de transferts des ressources s'achevant, la gestion future préconise le recours intensif aux ressources non conventionnelles, telles les eaux usées traitées et les eaux dessalées. Il s'agit là d'un des principaux leviers d'intervention que le Grand Sousse peut promouvoir pour une "gestion intégrée" du système hydraulique, en plus d'une gestion de la demande axée sur les économies d'eau. La thèse a mobilisé des enquêtes directes sur un échantillon représentatif de ménages, d'unités industrielles et d'hôtels ; elles ont permis de dresser le bilan des actions menées dans le sens de cette nouvelle orientation, et de mieux comprendre les contraintes et obstacles rencontrés. La cartographique a été un outil indispensable à la représentation de cette inadéquation entre offre et demande en eau, du réseau d'approvisionnement et de distribution, et des composantes de la gestion future de l'eau. La démarche prospective permet de tirer la sirène d'alarme sur la menace que fait peser l'évolution tendancielle de la demande sur les équilibres socio-spatiaux, et se propose des solutions alternatives à cette évolution
Grand Sousse, oriental part of Sousse governorate, shelters one of the most important regional metropolises of the country, with a concentration on the littoral fringe of the human and economic activities. The demographic explosion and the generalization of the sideboard in drinking water make an important home of water consumption. Now this region is also very marked by the aridity, the main cause of low local resources. Dependent on nearby regions for its water supply, Grand Sousse leads for a long time a running to the harnessing to satisfy growing needs. The traditional political strategy of mobilization and transfers of the resources ending, the future management recommends the extensive appeal to the not conventional resources, some treated waste water and desalinated waters. It is about one of the main control levers of intervention there which Grand Sousse can promote for an "integrated management" of the hydraulic system, besides a management of the demand centred on the savings of water. The thesis mobilized direct inquiries on a representative sample of households, industrial units and hotels; they allowed to draw up balance sheet actions led in the sense of this new orientation, and to understand better the constraints and the met obstacles. The cartographic was a tool indispensable to the representation of this inadequacy between supply and demand in water, the network of supply and distribution, and constituents of the future management of the water. The forward-looking approach allows pulling the air-raid siren at the threat that makes weigh the trend-setting evolution of the demand on the socio-spatial balances, and proposes alternative solutions of this evolution

Abstract:
Data center energy consumption can be divided into three broad categories: Information Technology (IT), Electrical, and Mechanical. An efficient data center uses the least amount of non-IT energy, which is typically divided between the mechanical and electrical systems. Mechanical systems generally contribute a large portion of the non-IT energy use by providing cooling from compressor-based equipment [1,2] and because of this, strategies to reduce compressor energy consumption can lead to significant mechanical system energy savings. The most efficient way to reduce compressor energy is through elimination or significant reduction in annual runtime. This is possible with the use of integrated airside or waterside economizers. This paper demonstrates the impacts of economization in data centers through data collected from four operating facilities over the course of implementing various economizer improvement projects. System architectures include water-cooled centrifugal chiller plant with waterside economization, direct expansion air handling units (AHU) with airside economization, air-cooled centrifugal chillers with integrated waterside economization, and direct expansion computer room air conditioners (CRAC) with evaporative cooling and waterside economization. A systematic and methodical comparison of the baseline and post-conditions is discussed, comparing expected to observed economizer operating conditions. The comparison of multiple real-world scenarios revealed a range of variances in expected operation of economizer sequences to actual observations, indicating a need for close monitoring of system performance by data center operators to fully realize economizer benefits within facilities.

Abstract:
With the soaring price of oil and the global push toward reduction in carbon emissions, renewable energy is treated by many as a solution to the economic and environmental cost of consumption of fossil fuels. With the power plant reviewed in this paper use of Solar and Bio-fuels will be attained. During the day power needs can be met with Solar energy and when that energy supply is not adequate can use bio-fuels or fuel of choice (gaseous or liquid). If there is a need for use only with Solar energy (i.e. peak power demand) can shut down and restart when desired. Due to the size of the unit, start up is not a long labor intensive task and can be accomplished within the hour. The 150 Kw Integrated Solar Combined Cycle (ISCC) power plant is for commercial and residential use. The unit will produce 150 Kw electrical power output to customer with Solar Thermal Energy (STE). Solar Thermal energy is attained from parabolic trough concentrator(s). Working fluid in the STE system is Syltherm 800 (Silicone Heat Transfer Fluid) is acceptable use from –40F to 750 F. This fluid is heated and passes through a heat exchanger to transfer energy to the closed rankine cycle (where the liquid is changed to vapor stage. Steady state analysis performed on the rankine cycle, with ammonia / water mixture (50/50) used NIST standard reference database 23 for the thermodynamic and transport properties REFPROP [1]. A unique feature with the combined cycle unit, is the rankine cycle turbine wheel is directly attached to the power producing gas turbine spool, thus share a common high speed permanent magnet alternator assembly. The core gas turbine engine used in the combined cycle is a two spool, high pressure ratio (11:1) simple cycle microturbine with cycle efficiency of 20%, at 70Kw output electrical power (sea level standard day). The latter is defined as model TMA 70SC. In addition to the gas turbine engine and rankine turbine stage, the combined cycle incorporates a gas turbine waste heat boiler, economizer, condenser and economizer fluid preheater. The combined cycle unit, without thermal energy, will produce 145Kw (sea level standard day) with an electrical output efficiency of 40%. The gas turbine exhaust to atmosphere will be less than 240 F. The ISCC unit power producing spool / rotor will operate at 100% N regardless of gas turbine power demand. Whereas, spool number one will vary with gas turbine power demand. When the available solar thermal energy decreases the gas turbine fuel flow will increase to maintain electrical power, pending day conditions. The ISCC power plant, can be used for main power plants in [stand alone] communities, business, industrial or distributed energy (D.E.). Also, will provide electrical power to the customer at lower rate than traditional power companies.

Abstract:
This work shows the study of different configurations of integrated solar combined cycle (ISCC) parabolic-trough power plant with Direct Steam Generation (DSG). This paper is a sequel of previous works (Duran), but in this case six different configurations are analyzed: two pressure level without reheater (2P), 2P considering the solar field the high pressure economizer of the heat recovery steam generator, 2P considering the solar field the low pressure superheater, two pressure level with reheater (2PR), 2PR considering the solar field the low pressure superheater, 2PR considering the solar field the high pressure economizer. The main objective is to achieve the thermoeconomic optimization (based on Thermodynamic 1st. Law) of the HRSG including the solar field, to determine the optimal design parameters of both systems. It is applied a genetic algorithm (GA) methodology employed in previous works for the optimization of combined cycle power plants. Also, a sensitivity analysis with respect to the variation of solar radiation is done for the configurations that yield better results. As a result it would be obtained the optimal parameters of the HRSG and the optimal solar energy contribution for the configurations analyzed.

Abstract:
Parabolic trough technology is currently one of the most extended solar thermal systems for the production of electricity. This paper describes a thermo-economic study of an integrated, combined-cycle parabolic trough power plant. The parabolic trough plant is considered an economizer or a superheater of the HRSG (heat recovery steam generator). The main objective is to obtain the optimum design of the different sections of the boiler and the size of the parabolic field. The configurations analyzed are two pressure levels with and without a reheater. A Euro Trough (ET) concentrator was used in this study, the working fluid being water with direct steam generation. There will be no problem with the evaporation in the absorber, since the solar plant will be the economizer of the HRSG and an approach point greater than 3°C is considered. The methodology applied for the optimization is Genetic Algorithms. This methodology was employed in previous works developed by the authors and yielded good results. So that method is applied to the configurations analyzed but including the parabolic trough plant. As a result, a thermoeconomic optimum design of a parabolic trough plant used as the section of the HRSG is obtained. The results show that the solar field increases the power and efficiency of the combined-cycle plant during the operation and makes it less susceptible to load variations.

Abstract:
Exhaust gas temperature in coal-fired power plants can reach approximately 120 °C to 140 °C, with the thermal energy accounting for approximately 3% to 8% of the total input energy. Therefore, the heat recovery of exhaust flue gas can improve the thermal efficiency of coal-fired power plants. Currently, the waste heat of flue gas can be recovered by installing an extra heat exchanger, also called low-temperature economizer (LTE), at the end of the boiler flue to heat a part of the condensed water. Extra work can then be obtained by saving the extracted steam and using it to heat the condensed water. However, the temperature of exhaust flue gas is only about 130 °C, which causes the flue gas to heat only the condensed water in the #7 and #8 regenerative heaters. Thus, the energy savings are inconspicuous. This paper proposes a novel flue gas heat recovery system to dramatically increase the temperature of flue gas in the LTE by comprehensive optimization of the air preheater and the LTE. A low-temperature (LT) air preheater can be installed after the LTE in the novel system so that the flue gas can be divided into two parts to heat the air. Simultaneously, the LTE can be installed between the two air preheaters, causing the temperature of flue gas in the LTE to reach above 170 °C. Hence, the temperature of condensed water in the LTE can be increased significantly. In addition, the LTE can replace the high-pressure extracted steam from the turbine, resulting in better energy savings. We also conduct case studies based on a typical 1,000 MW supercritical power generation unit in China. The results indicate better performance of the novel system, with a decrease in exergy loss and improvement in heat transfer characteristics. The reduction in standard coal equivalent of the novel system can reach 3.31g/kWh, nearly 2.4 times that of the system that uses conventional waste heat recovery. Our achievements provide a promising waste heat recovery methods of the utility boiler flue gas.

Abstract:
Selective catalytic reduction (SCR) technology is being increasingly applied for controlling emissions of nitrogen oxides (NOx) from coal-fired boilers. For many power plants, temperature control becomes an essential challenge to ensure optimal SCR performance and to keep the material integrity of the SCR structure. Progress Energy MAYO Plant has a tandem boiler design with a Gross Power Generation Capacity of 2 × 400 MW. The plant decided to change their coal source to a lower HHV type PRB coal and integrated Clyde Bergemann’s SmartClean technology to deal with the changes in the coal quality and ensure a stable flue gas temperature going into the SCR. The new SmartClean technology optimized the cleaning to control the Economizer Exit Gas Temperature (EEGT) at a desired set temperature. The results of the performance tests showed that the EEGT control was successful and the temperature profile stabilized after implementing the new SmartClean technology. The new technology derives decisions and changes the cleaning strategy based on the effect of the sootblowers on the heat transfer performance rather than the traditional approach of targeting a static cleanliness level in the boiler. The performance data of the closed loop tests are presented as well as the economical justification of the project.

Abstract:
Abstract The temperature of SCO2 fed to the boiler in SCO2 coal-fired power plants is relatively high, ∼500 °C. It leads to high boiler exhaust temperature, which is ∼120 °C according to previous studies. Waste heat recovery from low temperature fluegas in SCO2 coal-fired power plants is a key issue to be addressed to enhance power plant efficiency and electrostatic precipitator performance. Therefore, systems of waste heat recovery from low-temperature fluegas were proposed in this study. To evaluate the economic performances of the proposed systems and obtain the best system configurations, economic and thermodynamic models were developed. Moreover, multi-parameter optimization model based on Genetic Algorithm was developed. The waste heat recovery system is proposed and optimized by considering coupling and matching of the air preheating process, heat regenerative process and fluegas cooling process. With a 1000MW SCO2 coal-fired power plant as the reference case, thermodynamic and economic analyses were carried out. Results show that when the low temperature economizer is integrated together with the main compressor intercooling and flue bypass ahead the air-preheater, the temperature of exhaust fluegas can be decreased to ∼95 °C and the power plant efficiency can be enhanced by 1.39%-pts compared with basic system. Through the economic model analysis, the system levelized cost of electricity is 0.04158 $ kW−1 h−1.

Abstract:
With the ongoing technological progress new transportation and communication channels have emerged, and interactions between people and therefore states has increased significantly. As a consequence of this development the concept of globalization, meaning the disappearance of the boundaries between states, has arisen. Thus the process of integration between the economies of states has started, which increased the dependency and interaction of the state economies. Hence, an economics crisis appearing in a particular state effects all of the countries integrated to this integrated system. In this study it is aimed to research that in what degree the Eurasian economies are integrated to the world economy, and affected from the recent economic crisis. The changes of the growth rates of the economies of Eurasian states during the crisis have been considered in order to employ them in the analysis of these affects. Moreover, by considering the basic economic indicators of those states such as unemployment rate, consumer price index, budget deficit, current deficit, it is aimed that to reach a general view of those states economic positions.

Full text
Abstract:
In recent years, academic and industry areas are both show an interest in supply chain management (SCM). The globalization of competition, the reduce in product life cycle, time depending competition and quick exchanges make the firms think about re-designing their supply chains. With the view of these evolutions, firms decided that they must use information technologies in their SCM. In future, information flow will be the key factor to determine the levels and the difference between firms. Information flow occurs with the integration of information technologies with the systems. The success factor for a firm is to add value from gathering, operating and dispatching information and develop the work model to have this value. Processing this model depends on achieving information sharing between supply chain members. Information sharing is a critical factor between supply chain members. The data shared between supply chain members becomes useful information for the members. So, determining the shared data and measuring this share is an important issue. This study includes information sharing measurement model between integrated supply chain members. The model starts with gathering data with a survey and continues converting these quantitative data’s to qualitative data’s by structured equations. The qualitative data’s used in an artificial intelligence method, inductive learning. Rules extraction is made by an inductive learning method, RULESX. With these rules, information sharing among supply chain members can be measured and suggestions can be made to firms for improving their SCM’s. This model is sector-independent and can be easily applied.

Abstract:
As economies integrate into global and regional value chains, these fragmented production structures may not be adequately reflected in diversification measurements. While an assessment of export diversification using gross exports provides insight into the direct exports of a trading economy, it does not tell the full story. Using both gross exports and value-added exports can better inform policy decisions and enable exporting economies to carve their niche in increasingly digitally-enabled value chains.

Abstract:
Public investment in different types of tourism, from business to leisure tourism, has differentiated impacts on local economies, environment, people and government revenues. A fully integrated analytical approach such as the Integrated Economic-Environmental Modeling (IEEM) Platform is required to capture these multi-dimensional impacts. Applying IEEM to public investment in tourism in Costa Rica we find: investing in a higher skilled labor force particularly in traditional tourism-related activities will improve household welfare; similar increases in demand across all types of tourism show that Health tourism generates the greatest impact on household welfare, while Business tourism has the best prospects for reducing unemployment; Business tourism generates the largest increase in government revenues, but also has the largest greenhouse gas emission footprint, and; the whole of economy perspective of IEEM that captures direct, indirect and induced impacts results in a higher Net Present Value estimation of the investment.

Regional banking systems in Asia and the Pacific are not only increasingly integrated but also tend to be concentrated to a few counterparties only, exposing the region to financial risk and policy spillovers. This study assesses the determinants and impacts of the region’s cross-border banking concentration. It constructs and analyzes cross-border bank concentration measures for 47 economies in Asia and the Pacific from 2000 to 2019. Results suggest that higher capital account, trade openness, and per capita income are significantly associated with lower cross-border bank concentration. Moreover, elevated cross-border bank concentration tends to lower domestic credit growth and nonperforming loans.

Abstract:
Natural resources are an important source for development, and Latin America is one of the regions with the highest endowment. This calls for a reconsideration of resource-based development. Ambitious countries are moving toward high-value activities and more diversified economies to continue moving up the development ladder. In this sense, the resurgence of industrial policy can correct market failures and lead to the implementation of mission-oriented policies. This document analyzes opportunities to design and implement integrated policies through a revised taxonomy of mining-related policies, applying it to Australia, South Africa, and Chile. The mining sector has been a fertile field, characterized by high technology niches, growth, and innovation. Demand and supply policies can shape the path for development within the sector and across the economy due to the potential of vertical and horizontal linkages.

Abstract:
The conflict in Ukraine has generated a large inflow of refugees into European countries, with more than five million people having fled to neighboring countries. So far, the public response has been generally positive, with large shares of the European population being in favor of the policies implemented to host and support the Ukrainian refugees. In this note we look at the academic literature with the aim to: a) discuss which socioeconomic characteristics of the refugees are typically associated with positive or negative attitudes towards them; and, b) reflect on which policy measures can promote more inclusive and tolerant preferences. The evidence from the literature suggests that negative attitudes towards refugees can be widespread, but less so for those groups that are perceived to be in need of humanitarian help, are culturally closer to host communities, and more likely to contribute to the economies of the host country. Three policy measures to sustain a welcoming climate towards refugees emerge from the relevant literature: facilitate the interactions between host communities and those forcibly displaced; integrate the refugees into the society, including in the labor market; and provide simple, factual information about the refugees and their socioeconomic background.
