Abstract:

Solar aided coal-fired power plants utilize various types of solar thermal energy for coupling coal-fired power plants by using the characteristics of various thermal needs of the plants. In this way, the costly thermal storage system and power generating system will be unnecessary while the intermittent and unsteady way of power generation will be avoided. Moreover, the large-scale utilization of solar thermal power and the energy-saving aim of power plants will be realized. The contribution evaluating system of solar thermal power needs to be explored. This paper deals with the evaluation method of solar contribution based on the second law of thermodynamics and the principle of thermoeconomics with a case of 600 MW solar aided coal-fired power plant. In this study, the feasibility of the method has been carried out. The contribution of this paper is not only to determine the proportion of solar energy in overall electric power, but also to assign the individual cost components involving solar energy. Therefore, this study will supply the theoretical reference for the future research of evaluation methods and new energy resource subsidy.

Abstract:

This paper proposed using solar energy as the auxiliary heat source of coal-fired power plants’ auxiliary steam system based on the current status of the coal-fired power generation and solar energy utilization. Taking a 600MW coal-fired power unit as an example to analysis, it is shown that the thermal performance of the integrated system is improved and the coal consumption rate declines, which radically reduces power plants’ emissions of greenhouse gas and pollutants.

Abstract:

Energy saving in small-scale thermal power engineering is aimed at increasing the efficiency of using fossil energy carriers, electricity and, possibly, their wider replacement with alternative sources in the housing and communal complex. The practical use of solar installations, both photovoltaic and directly water heating, has found widespread use, at the same time, the peculiarities of the introduction of these installations are due to the climatic and technical conditions of their use. For countries located in climatic zones with relatively cold climates, the development of water heating installations is most rational when they are used seasonally. The relatively low potential of the coolant, the frequency of heat supply in these installations, associated with the seasonality of their operation, time of day and weather, necessitate a number of technical solutions using additional equipment in the form of thermal energy accumulators, heat pumps and other equipment, which in any case must be combined with a traditional source of thermal energy operating on fossil fuels or electricity, performing the functions of both an additional and emergency source of thermal energy. Reserving the capacity of alternative energy sources is most efficient and least energy-consuming to carry out with heat sources using gaseous or degasified fuel. The use of electricity for the purposes of heat supply, with small capital investments, requires significant installed capacities of the heat source with a low coefficient of efficiency for primary fuel. In order to achieve the highest efficiency of energy use, thermal schemes of autonomous heat supply installations for objects using modern condensing boilers of low power and, together with them, various heat storage devices, providing year-round operation of equipment at heat supply facilities, are considered.

Abstract:

The DISS (DIrect Solar Steam) project is a complete R+TD program aimed at developing a new generation of solar thermal power plants with direct steam generation (DSG) in the absorber tubes of parabolic trough collectors. During the first phase of the project (1996-1998), a life-size test facility was implemented at the Plataforma Solar de Almerı´a (PSA) to investigate the basic DSG processes under real solar conditions and evaluate the unanswered technical questions concerning this new technology. This paper updates DISS project status and explains O&M-related experience (e.g., main problems faced and solutions applied) with the PSA DISS test facility since January 1999.

Abstract:

The objective of this paper is to investigate the theoretical performance of Parabolic Trough Collector (PTC) using various nanofluids. The theoretical performances are calculated for Al2O3, graphite, magnetite, SWCNH, CuO, SiO2, MWCNT, TiO2, Fe2O3, and ZnO in water nanofluids. The heat transfer equations, thermodynamic properties of nanofluid and pumping power are utilised for the development of novel thermal model. The theoretical thermal efficiency of the PTC is calculated, and the economic viability of the technology is predicted for a range of nanofluid concentration. The results showed that the thermal conductivity increases with the concentration of nanoparticles in the base fluid. Magnetite nanofluid showed the highest thermal efficiency, followed by CuO, MWCNT, ZnO, SWCNH, TiO2, Fe2O3, Al2O3, graphite, and SiO2, respectively. The study reveals that MWCNT at 0.4% concentration is the best-suited nanofluid considering thermal gain and pumping power. Most of the nanofluids achieved optimum efficiency at 0.4% concentration. The influence of mass flow rate on thermal efficiency is evaluated. When the mass flow rate increased from 70 Kg/hr to 90Kg/hr, a 10%-20% efficiency increase is observed. Dispersing nanofluids reduces the levelized cost of energy of large-scale power plants. These findings add to the knowledge of the scientific community aimed explicitly at solar thermal energy technology. The report can also be used as a base to pursue solar thermal projects on an economic basis.

Abstract:

A range of energy technologies ultimately aimed at obtaining electric energy is considered. Proceeding from the list of considered sources, it is possible to analyze their different combinations for achieving better energy efficiency of new complexes. A systematic list of 21 currently known traditional, non-traditional, and renewable energy sources is compiled. Each of them taken individually has an efficiency not exceeding 50%, except for some types of fuel cell based power facilities. Block diagrams of energy flow conversion stages are proposed for the considered kinds of sources. Obviously, if some or other chain does not contain certain blocks in comparison with the first classical chain of thermal engine thermodynamic cycles, this means that the missing energy conversion stages of are either implemented covertly, or proceed in the environment. As an example, two promising sources are considered: an osmotic hydroelectric power plant and a hybrid power plant (HybPP) based on high-temperature fuel cells with solid oxide electrolyte and a gas turbine unit. In fact, an osmotic hydroelectric power plant takes the solar energy spent for evaporation from sea surfaces in the form of the osmotic pressure phenomenon energy under the conditions of one-way diffusion of fresh river water (a solvent) molecules through a semi-permeable membrane towards salt sea water (a solution). An osmotic HPP is a combination of a reservoir with semi-permeable membranes and an HPP. The former is characterized by the expected high specific power up to 12 kW per square meter of semi-permeable membrane area, and the latter is characterized by the highest efficiency among all types of electric power sources and by the high achieved specific power up to 2-3 kW per square meter of solid oxide electrolyte surface area.

Abstract:

This study presents a techno-economic assessment of the use of Linear Fresnel Solar Collectors for the heat supply in traditional fruits and vegetable processing industries in Almeria’s province. This assessment is justified by the high availability of solar radiation in the area under study, the evaluation of complementary energy self-consumption modalities, and the suitability of using local resources for the preservation and improvement of traditional productive activities. The work starts with an identification of the potential user’s needs and their location in the province. Afterward, the solar radiation resources have been estimated as they constitute one of the basic inputs for sizing the proposed systems. Together with the above, representative thermal demands have been considered and different configurations of commercial Linear Fresnel Solar Collector thermal plants aimed to contribute to solarize the analyzed productive processes have been designed and the corresponding techno-economic assessment have been undertaken. Main findings advance the profitability that can be achieved with this technology, reaching, after an optimized integration of the solar plant in the industrial process, a solar fraction between 66-82 % and payback periods of the investment between 6-12 years

Abstract:

The desire to increase the efficiency of existing renewable energy sources has been thoroughly researched over the past years. This meta study aimed to investigate existing methods used by previous researchers to increase the Specific Heat Capacity of Molten Salt used for Concentrated Solar Power Plants. Investigations into nanoparticles were explored because of the effect of particle size and concentration can potentially increase the specific heat capacity of the molten salt. Numerous nanoparticles have shown to improve the thermal properties such as Silica (SiO2), Alumina (Al2O3), Titania (TiO2). Our summation was that the addition of nanoparticles into Molten Salts shows an increase in desired thermal properties of the Molten Salts. An efficiency increase of up to 28% was noted in the SHC (Cp) of the Molten Salts when Nanoparticles of 60nm were introduced.

Abstract:

The ways of further transformation of the existing energy market in Ukraine under the conditions of biosphere compatibility are analyzed. The use of renewable energy sources is one of the most important directions of modern energy policy, aimed both at improving the state of the environment and at saving traditional fuel and energy resources. Adopted legislative and regulatory acts contributed to the rapid growth of "green" energy in Ukraine. Currently, the uncontrolled construction and commissioning of exclusively solar power plants at rates that are ahead of planned indicators have caused a threat to the energy security of our state. At the same time, other types of renewable sources, which in the vast majority can be used to balance the energy market, are underdeveloped. Waste from agricultural production, solid household waste landfills under certain conditions can be transformed from sources of environmental pollution into renewable energy sources with biogas generation. Its main components are methane and carbon dioxide. One of the promising ways to increase the efficiency of fuel use can be the synthesis of methane from hydrogen, which is obtained with the use of electricity from alternative sources, and carbon dioxide, which is formed during the production of biomethane. In this way, a complex problem is solved - the simultaneous loading of nuclear power plant units, the use of excess electricity from wind and solar power plants with a decrease in the balancing capacities of thermal generation. The meaning of the ecological and energy optimization process is not to replace one energy source with another, but economic and industrial transformation, decarbonization and decentralization. To solve these problems, measures are proposed to improve the requirements of the regulatory and legislative acts in force in Ukraine on the regulation of the state's energy sector by introducing greater competition, European technical standards and transparent regulatory rules, a better investment climate in the domestic market.

Abstract:

The article is aimed at modeling the energy market of Ukraine on the meso-level, identifying its features and development problems, forming a system of indicators for monitoring the development of electricity production at the regional level. It is determined that Ukraine produces electrical power mainly from non-renewable energy sources, namely fossil and mineral fuels, using nuclear power plants and thermal power plants, which comprises 54% of the total electricity production. Wind, solar sources of electrical power, biofuels and hydroelectric power plants make up a smaller part of production – 7%. It is noted that Ukraine annually consumes about 92 million tonnes of oil equivalent (toe) of energy, has a high level of energy intensity of the economy, therefore, in order to reach the world average level, it is necessary to reduce energy consumption by 50 million toe. The level of losses of the produced and imported energy during its transformation and transportation to the end user is 44%. The potential for reducing energy consumption during consumption in sectors such as housing, budget-based and energy supply is about 19 million toe. To assess the state of the energy sector in Ukraine in 2019, a grouping of regions of Ukraine was carried out using cluster analysis. The regions that have entered the 1st cluster, namely: Dnipropetrovsk, Donetsk and Zaporizhzhia regions, have the best prospects for the rapid innovative development of the energy market. The regions that are included in the 3rd cluster have the lowest values of energy sector development indicators among other clusters and require special attention to the development of new, cost-effective energy technologies. The system of indicators for the analysis of the energy market development on meso-level is substantiated. The proposed indicators are adapted to the indicators of monitoring the achievement of sustainable development goals, namely: sustainable development goals 7 «Ensuring access to inexpensive, reliable, sustainable and modern energy sources for everyone».

Abstract:

Anaerobic Digestion (AD) is a well-established process that is becoming increasingly popular, especially as a technology for organic waste treatment; the process produces biogas, which can be upgraded to biomethane, which can be used in the transport sector or injected into the natural gas grid. Considering the sensitivity of Anaerobic Digestion to several process parameters, mathematical modeling and numerical simulations can be useful to improve both design and control of the process. Therefore, several different modeling approaches were presented in the literature, aiming at providing suitable tools for the design and simulation of these systems. The purpose of this study is to analyze the recent advancements in the biomethane production from different points of view. Special attention is paid to the integration of this technology with additional renewable energy sources, such as solar, geothermal and wind, aimed at achieving a fully renewable biomethane production. In this case, auxiliary heat may be provided by solar thermal or geothermal energy, while wind or photovoltaic plants can provide auxiliary electricity. Recent advancements in plants design, biomethane production and mathematical modeling are shown in the paper, and the main challenges that these fields must face with are discussed. Considering the increasing interest of industries, public policy makers and researchers in this field, the efficiency and profitability such hybrid renewable solutions for biomethane production are expected to significantly improve in the next future, provided that suitable subsidies and funding policies are implemented to support their development.

Abstract:

In the article, investigation is given of the developed mathematical models of nonequilibrium in time and distributed in space thermodynamic state of Earth’s matter from its center to its surface depending on the cases of the presence and absence of an internal source of thermal energy concentrated in the center of mass taking into account known geophysical data about the nucleus, mantle, lithosphere and atmosphere, and endogenous and exogenous heat fluxes. The objects of research are as follows: mathematical models of geothermal energy of the Earth, its internal source, and heat balance of endogenous and exogenous heat fluxes on the Earth’s surface. Research methods used are as follows: thermometry in deep wells, ground and remote sensing of heat fluxes of the Earth and the planets of the Solar System, mathematical modeling of heat exchange and thermoelastic processes from compression of Earth’s matter by gravitational field energy information and classical physical and mathematical methods, and computer modeling. The aim of research: in computer modeling to provide new mathematical models that determine the geophysical parameters of geothermal energy, which are aimed on solving problems of energy, environmental and economic security of society, using modern technical means of calculating ground and remote sensing data development of geothermal resources, and regulation of the heat balance of the ecosystem, namely: (i) study of the geological structure of the lithosphere to a depth of 10 km by remote sensing to determine the physical parameters of its layers more accurately than ground methods; (ii) development of projects of geothermal power plants on the basis of single isolated wells of a given depth with a capacity of up to 2 ÷ 3 mW of electricity on continents of the globe; (iii) real-time monitoring and forecasting of the temperature field of the atmosphere according to its physical and chemical composition. The novelty of the obtained research results: (i) developed the mathematical model of the physical process of origin and distribution in the bowels of the density of geothermal energy of the Earth from the surface to its center, which is the density of internal energy of an elementary geological object, and which increases when approaching the center of the planet; (ii) developed the mathematical model of the thermal energy source of infrared (IR) waves of the elementary geophysical object of the Earth’s interior depending on the depth of its occurrence, which allows to determine the stable generation of geothermal energy by rocks in a deep well for extraction and conversion into electricity and to study the geological structure and physical properties of the Earth’s interior; (iii) the mathematical model of heat exchange between the layers of the Earth’s subsoil with the thermal energy of infrared waves according to the laws of Fourier thermal conductivity and Stefan–Boltzmann heat transfer, which together with the geothermal energy source model allows to determine a thermal capacity of rocks in a deep well; (iv) developed the mathematical model of stable action of a source of thermal energy in the center of mass of the Earth, in the absence of which it is hard to explain the power of its endogenous infrared heat flux, parameters of geothermal energy distribution in the Earth, and the current thermodynamic state of the atmosphere, and the change in temperature of which depends on the thermophysical parameters of the physical-chemical composition of the atmosphere more than on changes in the thermal activity of the Sun; (v) determination of new numerical values: thermophysical parameters of the Earth’s interior; kinetic, potential and own gravitational energy of the Earth and own gravitational energy of the planets of the Solar System.

Abstract:

With the increasing share of distributed energy resources on the electric grid, utility companies are facing significant decisions about infrastructure upgrades. An alternative to extensive and capital-intensive upgrades is to offer non-firm interconnection opportunities to distributed generators, via a coordinated operation of utility scale resources. This paper introduces a novel flexible interconnection option based on the last-in, first-out principles of access aimed at minimizing the unnecessary non-firm generation energy curtailment by balancing access rights and contribution to thermal overloads. Although we focus on solar photovoltaic (PV) plants in this work, the introduced flexible interconnection option applies to any distributed generation technology. The curtailment risk of individual non-firm PV units is evaluated across a range of PV penetration levels in a yearlong quasi-static time-series simulation on a real-world feeder. The results show the importance of the size of the curtailment zone in the curtailment risk distribution among flexible generation units as well as that of the “access right” defined by the order in which PV units connect to the grid. Case study results reveal that, with a proper selection of curtailment radius, utilities can reduce the total curtailment of flexible PV resources by up to more than 45%. Findings show that non-firm PV generators can effectively avoid all thermal limit-related upgrade costs.

Abstract:

In addition to wind and photovoltaic power, concentrating solar thermal power (CSP) will make a major contribution to electricity provision from renewable energies. Drawing on almost 30 years of operational experience in the multi-megawatt range, CSP is now a proven technology with a reliable cost and performance record. In conjunction with thermal energy storage, electricity can be provided according to demand. To date, solar thermal power plants with a total capacity of 1.3 GW are in operation worldwide, with an additional 2.3 GW under construction and 31.7 GW in advanced planning stage. Depending on the concentration factors, temperatures up to 1000 ° C can be reached to produce saturated or superheated steam for steam turbine cycles or compressed hot gas for gas turbine cycles. The heat rejected from these thermodynamic cycles can be used for sea water desalination, process heat and centralized provision of chilled water. While electricity generation from CSP plants is still more expensive than from wind turbines or photovoltaic panels, its independence from fluctuations and daily variation of wind speed and solar radiation provides it with a higher value. To become competitive with mid-load electricity from conventional power plants within the next 10–15 years, mass production of components, increased plant size and planning/operating experience will be accompanied by technological innovations. On 30 October 2009, a number of major industrial companies joined forces to establish the so-called DESERTEC Industry Initiative, which aims at providing by 2050 15 per cent of European electricity from renewable energy sources in North Africa, while at the same time securing energy, water, income and employment for this region. Solar thermal power plants are in the heart of this concept.

Abstract:

In recent years the problem of controlling the temperature of oil leaving an array of parabolic trough collectors has received much attention. The control schemes developed have in general utilized a feedback control loop combined with feedforward compensation. The majority of the published papers place the emphasis almost entirely on the design of the feedback control loop. Little or no attention has been paid to issues involved in the design of the feedforward controller. This paper seeks to redress this imbalance by concentrating upon the design and development of a feedforward controller for the ACUREX distributed solar collector field at the Plataforma Solar de Almeria. Different methods of combining feedback and feedforward will be assessed and experimental results will be presented in order to support any theoretical observations made.

Abstract: Energy comes in different forms. Light is a form of energy. So is heat. So is electricity. Often, one form of energy can be turned into another. This fact is very important because it explains how we get electricity, which we use in so many ways. Electricity is used to light streets and buildings, to run computers and TVs, and to run many other machines and appliances at home, at school, and at work. One way to get electricity is to This method for making electricity is popular. But it has some problems. Our planet has only a limited supply of oil and coal .In this method details about Endless Energy, Solar Cells Galore, Energy from Sun shine , Understanding Electricity. Solar Thermal power plant use the Sun as a heat source. In order to generate a high enough temperature for a power plant, solar energy must be concentrated. In a solar thermal power plant this in normally achieved with mirrors. Estimation for global solar thermal potential indicates that it could more than provide for total global electricity needs. There are three primary solar thermal technologies based on three ways no of concentrating solar energy: solar parabolic through plants, solar tower power plants, and solar dish power plants. The mirrors used in these plants are normally constructed from glass, a although, other techniques are being explored. Power plant of these types use solar heat to heat a thermodynamics fluid such as water in order to drive a thermodynamic engine; for water this will be a stream turbine. Solar thermal power plants can have heat storage systems that allow them to generate electricity beyond daylight hours.

Abstract:

Fundamental differences between the optimization strategies for power cycles used in “traditional” and solar-thermal power plants are identified using principles of finite-time thermodynamics. Optimal operating efficiencies for the power cycles in traditional and solar-thermal power plants are derived. In solar-thermal power plants, the added capital cost of a collector field shifts the optimum power cycle operating point to a higher-cycle efficiency when compared to a traditional plant. A model and method for optimizing the thermoeconomic performance of solar-thermal power plants based on the finite-time analysis is presented. The method is demonstrated by optimizing an existing organic Rankine cycle design for use with solar-thermal input. The net investment ratio (capital cost to net power) is improved by 17%, indicating the presence of opportunities for further optimization in some current solar-thermal designs.

Abstract:

Abstract With the rapid development of renewable energy, the demand for frequency regulation and peak shaving of coal-fired power plants is increasing. As the utilization hours of coal-fired power plants are gradually reduced, the economy of coal-fired power plants is gradually reduced. In order to improve the economic benefits of thermal power plants, thermal power plants are changing from the income model dominated by power generation to the income model of “cogeneration of power generation and auxiliary power service”. Among them, the energy storage system of Lingwu power plant of Ningxia electric power company of Guoneng group belongs to the first large-scale thermal power plant large-capacity solar thermal energy storage (flywheel) project at home and abroad. While ensuring the functions of conventional power supply, heating and cogeneration, the system can also provide auxiliary power services, support the safe and stable operation of a large power grid, and improve the flexibility and economic benefits of traditional thermal power plants. With the application of new technologies in coal-fired power plants, improving the economy of coal-fired generating units and power auxiliary services will be the main direction of power generation groups. At the same time, it also puts forward new requirements for power grid operation.

Abstract:

Studies completed at the Pacific Northwest Laboratory have allowed an in-depth examination of costs for solar thermal central receiver power plants. Central receiver concepts were evaluated for plant power ratings ranging from 0.5 to 100 MWe, and plant capacity factors ranging from 0.25 to 0.60. The large number of plant configurations considered necessitated the development of cost estimating models. Cost models were developed for concentrator, receiver, transport, storage, energy conversion, balance of plant, and O&M components. This paper presents a detailed discussion of costs for solar thermal central receiver power plants. Principal subcomponents and cost drivers are identified for each component. The impact of alternative design choices on cost and the tradeoffs involved between different working fluids are addressed. Cost uncertainties are examined qualitatively for each component. Finally, equations are presented for making preliminary estimates of direct capital and annual O&M costs for solar thermal central receiver systems.

Abstract:

Solar thermal power plants are an alternative for the future energy context, allowing for a progressive decarbonisation of electricity production. One way to improve the performance of such plants is the use of supercritical CO2 power cycles. This article focuses on a solar thermal plant with a central solar receiver coupled to a partial cooling cycle, and it conducts a comparative study from both a thermal and economic perspective with the aim of optimising the configuration of the receiver. The design of the solar receiver is based on a radial configuration, with absorber panels converging on the tower axis; the absorber panels are compact structures through which a pressurised gas circulates. The different configurations analysed keep a constant thermal power provided by the receiver while varying the number of panels and their dimensions. The results demonstrate the existence of an optimal configuration that maximises the exergy efficiency of the solar subsystem, taking into account both the receiver exergy efficiency and the heliostat field optical efficiency. The evolution of electricity generation cost follows a similar trend to that of the exergy efficiency, exhibiting minimum values when this efficiency is at its maximum.

Abstract:

Abstract Thermal-hydro-solar scheduling is the most difficult power system optimization issue in the modern day. The core mean of the arrangement of thermal-hydro-solar is to decide the most favorable power from thermal, hydro, and solar sources while meeting the various constraints of thermal, hydro, solar, and network. This paper describes the optimum hourly generation schedule plan in a thermal-hydro-solar power network utilizing particle swarm optimization (PSO) approach to attain the best or optimum solutions for scenarios involving three thermal power plants, four hydro power plants and ten solar photovoltaic (PV) plants. The conclusion of the simulation shows that the suggested PSO method seems to be able to minimize fuel costs, and emissions and has improved outcomes performance and strong integration than other approaches.

Abstract:

Solar power is a sustainable and affordable source of energy, and has gained interest from academies, companies, and government institutions as a potential and efficient alternative for next-generation energy production. To promote the penetration of solar power in the energy market, solar-generated electricity needs to be cost-competitive with fossil fuels and other renewables. Development of new materials for solar absorbers able to collect a higher fraction of solar radiation and work at higher temperatures, together with improved design of thermal energy storage systems and components, have been addressed as strategies for increasing the efficiency of solar power plants, offering dispatchable energy and adapting the electricity production to the curve demand. Manufacturing of concentrating solar power components greatly affects their performance and durability and, thus, the global efficiency of solar power plants. The development of viable, sustainable, and efficient manufacturing procedures and processes became key aspects within the breakthrough strategies of solar power technologies. This paper provides an outlook on the application of thermal spray processes to produce selective solar absorbing coatings in solar tower receivers and high-temperature protective barriers as strategies to mitigate the corrosion of concentrating solar power and thermal energy storage components when exposed to aggressive media during service life.

Abstract:

The solar chimney power plants produce electricity and thermal heat using the solar radiation. The thermal study of the solar chimney power plants is required since these systems are characterized by their high costs. This paper focuses on the study of a solar chimney power plant coupled with a turbine to increase the generated power. Thus, four turbine diameters are proposed. For each configuration, the distribution of the magnitude velocity, the air temperature, and the pressure was discussed. The results indicate that the generated power increases with the increase of the turbine diameter. This technical solution is identified interesting for designers to increase the generated power.
