Streszczenie:

A smart meter is an electronic device that accurately tracks your energy consumption and transmits that data to your energy provider so that you can be billed. The smart meters allow the central system and the meter to communicate in both directions. This two-way communication feature distinguishes the advanced metering infrastructure (AMI) in this case from automatic meter reading (AMR). This paper employs a hybrid system based on the Zigbee protocol, the Zigbee used to send messages between the smart meter and the utility company. To successfully complete tasks in this scenario, a cooperative communication system utilizing TDMA is used. The outcomes of Zigbee performance are measured using well-known metrics, also known as performance metrics. Many performance indicators have been chosen for performance evaluation: throughput, average end-to-end delivery ratio, and (PDR). The following conclusions were reached: End-to-end latency was 5.01 milliseconds, throughput was 42.63 kbps, and PDR was 97.19 percent. The network simulator successfully reads and wirelessly transmits voltage or power consumption using the Zigbee protocol and a cooperative communication system.

Streszczenie:

Cooperative decision-making has always benefited from achieving objectives subjected to system constraints in a microgrid. This paper considers the power balance between generation and load as a significant power quality issue. Hence, frequency regulation is regarded as a primary challenge in the system. When the system operator works towards profit for the power producer, an integrated operation provides a solution. The sources considered in this system are Solar PhotoVoltaics (SPV), FuelCells (FC), Diesel Generators (DG) and Battery driven Electric Vehicles (BEV), where the BEVs operate in Vehicle microgrid mode. A central controller and local controllers are present to operate the generators at desired levels. A cascaded fuzzy controller is designed that chooses the best suitable BEV to be connected to the microgrid. The system is implemented in a MATLAB Simulation environment, and various scenarios and cases have been considered for evaluating the system response and its sustainability.

Over the past few years, China has been increasingly active in promoting solar, wind, small hydropower and other clean technologies (from electric vehicles to smart grids) in Central Asia, where demand for a green transformation is high and the potential for clean energy is enormous. Beijing’s involvement in the development of the renewable energy industry in the region is intended to strengthen China’s international image as a responsible great power promoting the green transition, promote the implementation of Chinese rules, norms and standards in the field of clean energy, and expand the export opportunities of Chinese manufacturers of green equipment and technologies (including the so-called “three new products”— photovoltaic products, electric vehicles and lithium-ion batteries), open up new opportunities to meet China’s energy needs. The article focuses on cooperation between China and Central Asian countries in such areas as the development of solar and wind energy. The article demonstrates the interest convergence of the parties in the development of clean energy, determines the role, scale and forms of China’s participation in the promotion of solar and wind energy in the region.It is concluded that at the present stage, China’s role in financing solar and wind energy projects in the region is limited (especially in comparison with the scale of financing coming from multilateral development banks and national development and international cooperation agencies of Western countries), while the presence of Chinese companies as contractors and equipment suppliers in the construction of solar and wind power plants in Central Asia is very significant.

Streszczenie:

The integration of renewable power supplies into existing electrical grids, or other major technology transitions in electric power, is a complex sociotechnical process. While the technical challenges are well-understood, the process of adapting electricity policy and market rules to these new technologies is understudied. Planning and market rules are a critical determinant of the technical success of renewable energy integration efforts and the financial viability of renewable energy investments. Organizational adaptation can be particularly complex in electric power, where transmission grids cross multiple political boundaries and decisions are made not by central authorities or governments, but in cooperative regional frameworks that must accommodate many divergent interests. We add to a recently emerging literature on the governance of regional organizations that plan and operate electric power grids by developing and illustrating a novel approach to the study of political power in multistakeholder electricity organizations. We use semistructured interviews with participants in a specific regional electric grid authority, the PJM Regional Transmission Operator in the Mid-Atlantic United States, to elicit perceptions of where tensions arise in stakeholder-driven processes for changing PJM’s rules and perceptions of those groups of stakeholders that possess political power. We treat these perceptions as hypotheses that can be evaluated empirically using five years of data from PJM on how stakeholders voted on a wide variety of regional electricity policy issues. Representing voting behavior as a network, we use a community detection method to identify strong coalitions of stakeholders in PJM that provide support for some stakeholder perceptions of political power and refute other perceptions. The degree distribution of the voting network exhibits a fat tail relative to those in other canonical graph models. We show, using relatively simple network metrics including degree, betweenness, and the mixing parameter, that the reason for this fat tail in the degree distribution is the existence of “swing” voters in RTO stakeholder networks. These voters are identifiable in the tail of the degree distribution of the voting network and are influential in pushing highly contentious rule change proposals towards passage or failure. The method we develop is generalizable to other contexts and provides a new framework for the study of regional electricity policy formation.

The state parameters of electrical equipment and power system control parameters are the key data to realize the precise control and cooperative autonomy of a cyber physical power system. The trustworthiness of the data is the primary condition to guarantee the electric power system’s safe and reliable operation. In the traditional centralized data acquisition and management architecture, the security and trustworthiness completely depend on the central main server. A small mistake in the main server will result in data loss, which is irreversible and fatal. Blockchain technique combines the dispersed data with mutual backup and retrieval mechanism, which guarantees that the data cannot be tampered with and forged privately. Based on the blockchain technology, this article proposes a novel data trustworthy acquisition model with high credibility, applied to a self-organized cyber physical power system. In order to overcome the long time-consuming process of building traditional blockchains, a new on-demand data transmission routing algorithm with M/M/1/k queuing model is proposed in this article. Different scales of IEEE standard bus systems are employed as experimental examples to evaluate the algorithm’s performance. The results show that the proposed algorithm can effectively shorten the time consumption of blockchain construction and realize the data trustworthiness of cyber physical power system.

Objectives: The rapid development of central heating service in China mostly uses fossil fuels such as coal for production. The market competitiveness of new energy such as wind and solar energy to replace coal to produce heat energy for heating is relatively poor. Under the multiple requirements of energy security, ambient air quality and low carbon, electric heating is practicable because of its flexible use, adapts to the differential demand of consumers for heat, which energy supply can improve efficiency with the progress of power generation technology and so on. On the basis of case study data and results of residential users, companies and public buildings adopting electric heating technology, the analysis of consumer demand, supply chain structure and market relationship in China's electric heating market, this paper discusses the supply chain cooperation model by using revenue sharing contract mode. The results show that the performance of the benefit sharing ratio in the data simulation is acceptable when the revenue sharing contract is used in the supply chain. This model can promote the spontaneous and effective operation of the market, and help the local government in China to get rid of the embarrassment of the continuous subsidy.

Located in the center of Central Asia, Uzbekistan has become an important link in Beijing’s transport and logistics projects developed within the framework of the Chinese “One Belt, One Road” initiative. After Sh.Mirziyoyev came to power in the republic in 2016, there was an intensification of cooperation between the two countries, which contributed to the transformation of China into the main trading partner and investor of Uzbekistan. Based on the results of meetings between the leaders of the People's Republic of China and the Republic of Uzbekistan in 2023-2024. agreements were concluded that significantly strengthened the Chinese presence in the Uzbek economy and humanitarian sphere. Currently, one of the priorities of economic cooperation between the two countries is the electric power industry, with a special role being given to China’s assistance in the development of “green energy” in Uzbekistan. The growing dependence on China, and not only economic, limits the multi-vector foreign policy that Uzbekistan and other Central Asian countries have proclaimed.

The electrical market scenario has changed drastically in the last decade. In the presence of increased competition and less tolerant players, more sophisticated methods are required to balance the diversity and differential pricing while promoting cooperation among the agents. In the monopolistic environment, the central utility incurred the total cost of the transmission expansion. But as the current scenario demands, there are several public and private market players. The growth will benefit all the players, so the total cost in transmission expansion can be divided among players as per the benefit received by each player. In this paper, a transmission system expansion planning problem in the cooperative environment using cooperative game theory (CGT) is framed for the power sector, in which various players can cooperate in a coordinated manner to maximize their benefit but ultimately strengthen the power grid. In this paper, we have modeled, analyzed and compared various cost allocation methods of cooperative game theory specifically for the cost allocation in a transmission expansion planning problem. The present work focuses on forming coalitions to calculate the costs using the forward search and frog leap optimization approach. We have compared the SCRB, BSV, ENSC, and ACA methods for transmission expansion planning while attempting to satisfy the axioms. We have also observed that bilateral Shapely value efficiently allocated the costs due to its decentralized approach and the sequencing of coalition formations to achieve the best possible cost allocations.

Streszczenie:

The adoption of plug-in hybrid electric vehicles (PHEV) as a means of transportation over conventionally fueled vehicles introduces new challenges to the existing infrastructure of the electrical transmission and distribution system. PHEV battery charging can represent a significant power demand that has the potential to overload electrical distribution components. This study examines the impacts of PHEV charging on household service transformers, distribution conductors and voltage levels of a Central California residential distribution system. The system is simulated using ETAP power system analysis software. Transformers are the most vulnerable to overloads, especially if PHEV charging occurs in clusters. Main feeder conductors will be overloaded if a large amount of high power, quick charging occurs. Branch conductors will not be affected by PHEV charging. Based on current PHEV market projections for the region this study shows that significant equipment overloads are not likely to occur until well after 2017.

Streszczenie:

Norway and the EU have in recent years established ambitious goals to increase the share of renewable energy in their consumption. On account of these goals, a large-scale wind power development can be expected in northern Norway and Sweden. This development may be financed both by Norway and by countries with less wind resources in order to meet the energy goals imposed upon them. An increased power surplus is dependent on TSOs' abilities to transmit increased amounts of power through the Nordic grid. A scenario of likely power market conditions in year 2025 is used as a basis. The scenario has a high expectancy of new wind power as well as strong grid investments compared to the level in 2009. This thesis assumes an additional increase in annual renewable power production of 22 TWh, divided into 16 TWh in northern Norway and 6 TWh in northern Sweden. Results show that this amount of new power cannot be implemented without large grid investments. The Energy and Power Flow model is utlized to simulate the Nordic power flow for different levels of grid investments. Two grid solutions are proposed that allow the production increase while maintaining an acceptable state of system operation. The first uses DC transmission from Rana to Oslo in order to control power flow through Norway. An additional AC line from Kobbelv to Ritsem allows import from Sweden to the DC line. The second grid solution uses AC line upgrades throughout Norway ensuring two 420 kV lines from Ofoten to Kristiansand. Due to lower impedances in the Swedish grid, a large amount of the Norwegian production flows into and through Sweden. This solution requires a new line from Kobbelv to Ritsem and Rätan to Borgvik in order to solve resulting Swedish transmission congestion. Both grid solutions require a new DC cable from southern Norway to Germany in order to export most of the new power production. These cables require a number of supporting line upgrades in the region. Power producers schedule according to the new market situation, allowing a very high export during daytime and a low export during night. The increased power production in northern Norway and Sweden replaces other production. A high amount of gas and coal power is replaced in continental Europe. No hydropower, wind power or nuclear power is replaced. The DC and AC grid solutions allow European reductions corresponding to 19,3 % and 16,6 %, respectively, of the expected Norwegian CO2 emissions in year 2025. The cost of each grid solution is calculated to 22 760 MNOK and 19 310 MNOK. Annual system increases in valued socio-economic benefit outweigh the grid investment costs of each option by 3 300 MNOK and 3 370 MNOK per year of the period of analysis. The total cost of new power production must not exceed these values for such a decision to be socio-economically beneficial. Due to the high increases in calculated socio-economic benefit, a recommendation for further analysis is made.

Thesis (M. Tech. Electrical engineering) -- Central University of technology, Free State, 2012
Infrared thermography is a non-contact method of identifying the thermal behaviour of various plant equipment and machines, including their components, qualitatively via pattern recognition and quantitatively via statistical analysis. This allows for the development of condition monitoring and predictive failure analysis. It is well established that optimized maintenance planning can be more effective when a problem is detected in the early stages of failure. For example, in electrical systems an elevated electrical resistance caused by loose or corroded connections, broken conductor strands and dirty contact surfaces, results in localized heating, and a unique infrared pattern when analysed leads to the location of the problem and an indication of its severity. In recent years industrial thermography has used infrared detectors in the long wave portion of the electromagnetic spectrum normally between 8μm and 15μm, due partly to the fact that these wavelengths are not susceptible to solar radiation and/or solar glint. A number of scientific experiments were carried out on test apparatus to improve the understanding of the impact of convection, ambient air temperature and relative humidity on resultant infrared thermal images. Two similar heat sources, simulating a hotspot, at different temperature settings were used to determine whether the hotspot temperature should also be considered in conjunction with the atmospheric elements. The need for these experiments has also been identified by EPRI (Electrical Power Research Institute) in the USA as necessary to develop international severity criteria, and it is hoped that this study will contribute to this goal.

s grid and studies related to its improvement had been a great concern, so is the reason that main subject of my thesis became as &ldquo
Power System Frequency Control&rdquo

load control loops at power plants, reserve power and its provision even at the minimum capacity generation stage, (primary control) are the fundamental concerns of this subject. The adjustment of proper amount of reserve at the power plants, and correct system response to any kind of disturbance, in the overall, are measured by the quality of the frequency behaviour of the system. A simulator that will simulate a dynamic gas turbine and its control system model, together with a combined cycle power plant load controller is the outcome of this thesis.

A number of alternative economic and economic geography theories have been developed to account for the divergence of national political economy and industrial dynamics. These include the varieties of capitalism, developmental state, neo-Schumpeterian innovation, and Gerschenkronian catching-up theories. In this thesis I shall argue that in these theories a core and often shared concept of "institutional advantage" plays a central role in explaining different economic performances across nations. This concept is elaborated as a means of examining the causal relationships between institutional advantages and four necessary functions (market creation, capital mobilisation, process innovation and cost reduction) in the development of the photovoltaic (PV) industry of Germany, China, and South Korea. The development of these industries is examined in detail on the basis of empirical evidence in the form of archival and interview based data. Two main conclusions are reached. Firstly, domestic market creation is not a generally necessary condition for the development of a local PV industry at a national level. China's PV industry grew fast without a sufficient domestic market unlike in Germany. However, domestic market creation is important, because the domestic PV industry, national support policy and the domestic market are interrelated. Secondly, capital mobilisation is a core function in establishing the PV industry. In the 2000s, Korea failed to establish its local PV industry despite an institutional advantage in creating domestic markets, mainly due to the fact that it had an institutional disadvantage in mobilising capital. However, Germany and China succeeded in mobilising capital in their PV sectors, governments playing a decisive role in facilitating the raising of funds in both cases. This research contributes to a better understanding of the nature of industrial dynamics in the context of institutional configurations of a national political economy, broadening the usage of "institutional advantage" by applying this concept to comparative analysis on the national PV trajectories. Moreover, from the perspective of the social system, four necessary functions for the PV industry have been proposed and investigated.

The decreasing availability of fossil fuels and their negative environmental impacts requires urgent need of developing renewable energy. The main objective of this research was to develop low-dimensional nanomaterials for harvesting solar and mechanical energy with high conversion efficiency. In particular, photoelectrochemical water splitting and photovoltaic cell applications driven by sunlight were investigated in this project. A highly efficient triboelectric nanogenerator was investigated for harvesting mechanical energy. The device was further integrated with an organic solar cell for harvesting both mechanical energy and solar energy. My research work started with the synthesis of nanostructured materials. Electrospinning, as well as electrospray, was developed to synthesise nanofibres and hollow hemispheres. The influences of processing parameters to the morphologies and structures of the nanomaterials were systematically investigated. An electrophoretic deposition method was also developed to form good-quality nanostructured metal oxide thin films, which were applied in photoelectrochemical water splitting. The metal oxide hollow hemisphere thin films were also applied in dye-sensitised solar cells. A transparent and flexible triboelectric nanogenerator was developed in order to harvest mechanical energy. The contact electrodes were created using metal nanowire percolation networks embedded in a polymer matrix. The correlation between the energy conversion performances and optical property of the triboelectric electrodes were comprehensively studied as a function of the areal fraction of the metal nanowires. A flexible hybrid cell, integrating the solar cell with the triboelectric device, was designed by constructing an organic solar cell under a single-electrode triboelectric nanogenerator. The hybrid cell could convert both solar and mechanical energies into electricity independently and simultaneously. Such devices are potentially able to supply electricity day and night. Nanomaterials offer novel approaches for enhancing the efficiency of harvesting solar and mechanical energy in a hybrid device.

Resumo: Este projeto busca relacionar diversos aspectos interdisciplinares envolvidos em uma central de co-geração de energia elétrica. Motivado pela crescente inserção de centrais de geração distribuída operando de forma ilhada ou paralela ao sistema, foram desenvolvidos modelos mecânicos (térmicos e dinâmicos) e elétricos buscando representar os diversos equipamentos envolvidos em uma central de geração em um nível industrial. Baseado nesta concepção, optou-se pela geração de energia através de máquinas térmicas (turbinas a vapor) impulsionadas pela energia proveniente da queima de biomassa restante de diferentes processos industriais. Os modelos teóricos aqui representados foram numericamente simulados com parâmetros obtidos em um estudo de caso real. Seus resultados foram então comparados qualitativamente e quantitativamente contra as variáveis reais do processo analisado. Ao consolidar esta ferramenta de estudo, o simulador mostrou-se eficiente no treinamento de operadores de casas de forças, sendo capaz de esclarecer as interferências entre o nível de carga com as demais variáveis envolvidas em seu processo
Abstract: This project intends to gather several interdisciplinary aspects common to a co-generation power plant. Driven by the increasing amount of distributed generation units operating on island or parallel mode with the network, some mechanical (thermo and dynamic) and electrical models were developed in order to represent the equipments usually installed on an industrial size power station. Based on this concept, the more convenient option was to proceed the evaluation through turbo machinery (steam turbine) driven by the energy acquired from the heat power on burning byproducts of industrial processes. The theoretical models were simulated with parameters obtained from a real case study. The results were then finally compared with real process information acquired from field research. In order to consolidate this computational tool, the simulator has shown efficient results on training power station operators on clarifying the impacts of load level on the other relevant variables on their processes

Streszczenie:

Since the early 1990s electricity reforms across Sub-Saharan Africa have been marked by controversy. Despite the World Bank's major role in driving electricity reform as part of its conditional lending strategy in the electricity sector, its relationship with recipient countries has received little attention within the electricity reform literature. This is surprising given the increasing pressure on the World Bank to improve the effectiveness of its conditional lending more generally. This thesis contributes to filling this gap by exploring how World Bank-recipient country relations shape and constrain the direction of reform. The donor-recipient relationship is commonly espoused in the academic literature as a principal-agent relationship, whereby international aid organisations (principals) delegate authority for implementing their development policies to recipient countries (agents). I develop this framework by incorporating refined concepts of power, partnership, ownership and knowledge, prominent features in development studies literature and recent donor discourse. The analytical framework developed is applied to the process of electricity reform in two countries: Tanzania and Ghana. While the impetus for reform in these two countries was similar, the way in which the reform process unfolded was different. The analysis is based on in-depth, semi-structured interviews and documentary evidence. It uses a process-tracing method, combining within-case and cross-case analysis. A number of insights emerge from the analysis. I find that availability of reform expertise plays a significant role in determining the strength of power relations between donors and recipient countries. It also appears that reform ownership lies within different ‘domains'. Uneven ownership across domains accounts for the inconsistent reform implementation noted in both cases. And knowledge asymmetry provides a useful concept to analyse the impact of decentralised donor staff. In conclusion, this thesis argues that a modified principal-agent framework offers additional insight into the workings of the donor-recipient relationship.

Streszczenie:

AbstractAchieving the urgent need for rapid decarbonization to meet the 1.5 °C target requires disruptive technological change. In the automotive industry, technological progress is closely linked to improved sustainability, and sustainability goals drive the need for technological innovation. However, new technologies in the mobility sector are fraught with uncertainties that challenge both original equipment manufacturers (OEMs) and their stakeholders, such as suppliers, customers, and policy-makers. Therefore, this chapter focuses on the technical, economic, and environmental evaluation of alternative powertrain concepts and the management of uncertainties associated with emerging technological innovation as part of the broader transition to net zero.Electric mobility plays a central role in the sustainability transition and is characterized by a high degree of variance. Battery electric vehicles (BEVs) are expected to dominate private transport in the future due to their greenhouse gas and pollutant-free operation and high efficiency. In addition to charging infrastructure, the technical challenges currently lie primarily in cell chemistry and power electronics. Advances in battery technology and infrastructure electrification will help eliminate the range problem in the future. Another important future fuel is hydrogen. One application is the fuel cell vehicle, which combines the advantages of a chemical energy carrier with high gravimetric energy density with those of an electrical energy converter. Hydrogen also plays an important role as an energy carrier for specific energy supply processes in manufacturing processes and simplifies the transport of regeneratively generated energy. In addition, hybrid vehicles are a transitional technology, and alternative fuel internal combustion engines can contribute to the decarbonization of the existing fleet and to specific applications.This chapter assesses the performance of alternative powertrains; highlights the interrelationship between powertrain systems, energy ecosystems, and sustainability goals; and identifies future research directions for electric and hydrogen mobility.

Streszczenie:

In The work of nations: preparing ourselves for 21st-century capitalism Reich considers technological innovation as a close relationship between new technologies and new human capital, to determine the standard of living of workers and a central point is differences between skilled and unskilled workers. In this context the Unions, born as a representation of the homogeneous work of mass production, would lose their centrality in favor of the politics, i. e. of liberal democratic élites. In latest Saving capitalism: for the many not for the few, Reich discovers again the central role of Unions of workers, at company level, both in cooperative and real power terms.
