Resumen

Since the 21st century, China's power industry has been developing very quickly, and the generated electrical energy has been growing rapidly. Although nuclear power, wind power, solar power generations have been increased, thermal power generation still accounts for more than 80% of the total generating capacity. Thermal power provides an important material basis for the development of the national economy. Therefore, the prediction research on China's thermal power generation trend is becoming a topic of great interest. The fuel of thermal power generation-coal, is an exhaustible resource. Due to the exhaustible constraints the fuel, thermal power generation trend is bound to show a similar trend bell curve as the coal production trend, similar to a bell-shaped curve—a gradual increase to maximum output and then a short peak and a gradual decline. To get more accurate results of future thermal power generation, this paper applies the generalized Weng model to forecast China's thermal power generation peak and trend. The result indicted that the peak of China's thermal power generation appears in 2022 with generating capacity of 51,702 TWh. The generating capacity of thermal power will decrease gradually after 2022. Based on the results, the paper proposes some policy recommendations for the sustainable development of China's electrical energy. China should decrease the percentage of the capacity which comes from thermal generation and reduce the dependence on thermal power generation. Moreover, nuclear, hydraulic, wind and solar power should be developed before the thermal power generation peak.

Resumen

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.

Resumen

We have available to us an abundant, free energy resource: the sun delivers more energy to the Earth in one hour than humanity uses in an entire year. However, solar power only accounts for about 0.7% of the world’s energy supply (US Energy Information Administration, 2013). Even in Victoria the solar resource is world class, with average annual irradiance on par with the sunniest parts of Europe. The north-west of the state has a solar resource as good as Arizona, California and Nevada, but in 2012 solar electricity only provided 1.1% of our electricity demand (Clean Energy Council 2013, Renewable Electricity in Victoria Report 2012).

Resumen

In this paper, the photo-thermal power generation model is obtained by studying the operation process of solar radiation , light and thermal power generation equipment. By solving the gray model parameters by particle swarm optimization, a prediction model of light and heat generation based on G (1,1) optimization is proposed. In the case of example analysis, the amount of electricity generated by the solar radiation in the past few years was based on the photo-thermal power generation model, and the light and thermal power generation prediction model is used to obtain the photo-thermal power generation in the next few years.

Resumen

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.

Resumen

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.

Resumen

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.

Resumen

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.

Large capacity heat storage system with relatively mature technology and low cost can be configured to ensure stable and controllable power generation. The method can be. Solar thermal power generation has become a strategic emerging industry supported by many countries around the world. Spain, the United States, India, South Africa and other countries have carried out commercial operation of power technology with solar thermal, and installed capacity is growing steadily. China has also given key support to CSP generation technology, which has been vigorously developed. As the most promising new energy technology, CSP generation from molten salt heat storage tower is one of the main technical approaches of CSP generation. The key is to store the absorbed solar heat through thermal storage materials and release it stably for a long time, so as to achieve continuous and stable power generation independent of solar radiation changes. Through analysis, this paper puts forward the key technology research and scheme of molten salt regenerative CSP generation system, promotes the research on the bidirectional relationship between CSP station and power grid, and realizes the innovation of renewable energy technology.

Resumen

Solar energy has many advantages, such as being abundant, clean and environmentally friendly. Solar power generation has been widely deployed worldwide as an important form of renewable energy. The solar thermal power generation is one of a few popular forms to utilize solar energy, yet its modelling is a complicated problem. In this paper, an improved bare bone multi-objective particle swarm optimization algorithm (IBBMOPSO) is proposed based on the bare bone multi-objective particle swarm optimization algorithm (BBMOPSO). The algorithm is first tested on a set of benchmark problems, confirming its efficacy and the convergency speed. Then, it is applied to optimize two typical solar power generation systems including the solar Stirling power generation and the solar Brayton power generation; the results show that the proposed algorithm outperforms other algorithms for multi-objective optimization problems.

Resumen

This paper aims to investigate the properties and microstructure of Al2O3-SiC-ZrO2(ASZ) composite ceramics for solar thermal power generation. The composite ceramics were prepared from α-Al2O3, partially stabilized zirconia (Y2O35.2 wt%) and silicon carbide fired at 1280 °C for 2 h through pressureless sintering. Influence of the contents of SiC and ZrO2on the performance of ASZ composite ceramics have been observed and extensively investigated via XRD, SEM, etc. The results revealed that the thermal shock resistance and high-temperature thermal properties would increase with the increase of the SiC content. No cracking occurred after 30 times thermal shock (from room temperature to 800°C with air cooling) while the bending strength after thermal shock test, the thermal expansion coefficient, the heat capacity, the thermal conductivity coefficient and the thermal conductivity were 76.99MPa (with a growth rate of 27.89% after thermal shock), 5.85×10-6°C-1, 1.05 kJ(kgK)-1, 0.01 cm2s-1, 2.26 W(mK)-1, respectively. The XRD patterns indicated that the main crystal phases included corundum, silicon carbide and zirconium silicate while the SEM images illustrated the well-grown crystal grains had the sizes distributed among 5-120 μm.Key words: Al2O3-SiC-ZrO2composite ceramics, Silicon carbide, Thermal properties,Microstructure, Solar thermal power generation

Resumen

Recently, the use of novel renewable energy has attracted attention for suppressing the generation of carbon dioxide to prevent global warming. There is growing interest in energy reduction in buildings using solar energy because of its ease of use and repair and excellent maintenance. Therefore, in this study, air-based Photovoltaic thermal (PVT) systems, which can increase the utilization of solar energy, are compared with the existing PV system through measurement. PVT systems can increase the amount of power generation by lowering the temperature of the panel using air passing through the lower part of the panel. It is also possible to use the heated air obtained from the panel as indoor heating or for supplying hot water in a building. As a result of measuring the performance of existing PV panels and PVT panels under the same weather conditions, the power generation efficiency of PVT panels through which air passes increases compared to PV panels. Overall, an air-based PVT system can utilize solar energy about three times more than existing PV systems by utilizing solar heat and solar power. In summer, thermal collection and power generation by PVT were 51.9% and 19.0%, respectively, and power generation by PV was 18.0%. In contrast, the amount of thermal collection and power generation in winter was 43.5% and 20.3%, respectively, and the amount of power generated by PV was 18.7%. As such, it is necessary to review methods for utilizing the increase in power generation in winter and thermal collection in summer.

Resumen

Combined solar thermal and electric system is a combination of solar thermal system and solar electric system, such that both electric power and hot water can be produced at the same time. The solar collecting system includes a concentrator, frames, and a solar tracking system. The hot water system includes a flat collector, flow channels, water tubes, a storage tank, and a water pump. The power generation system is composed of thermoelectric modules and the associated controller. A miniature system was established and its performance was tested in this study. It was found that at the solar radiation flux of 800 W/m2, a total efficiency of 50% could be achieved. However, most of the solar energy has been converted to thermal energy instead of electricity. Our thermal electric system’s total efficiency can reach 43% and power generation of thermoelectric modules is only 0.6%.

Resumen

In day today life because of lack energy resources man move towards renewable energy source. When we go towards solar system it can use the sun energy to boil water or to generate electricity. Our aim is to develop a system which uses solar energy in both form thermal and solar form. The Hybrid Solar Solution is able to produce more electricity than PV, more reliable hot water than solar thermal, and heating at a better CoP than most conventional heat pumps - all with little or no CO2 emissions. Current projections suggest that a PV-T will produce sufficient electricity over the course of the year to cover the demand of the heat pump, which will meet a reasonably insulated building's total annual heating and hot water requirements. Further to this the incorporation of a solar thermally charged. The efficiency of the system to a point that it outperforms any thermal system or solar system.

Resumen

Objective: To improve the efficiency and stability of the solar thermal power generation system, and promote the optimization and development of solar thermal power generation grid connection. Methods: The working principle of the heat exchanger in the heat storage system is analyzed. Combined with the technological requirements of the system, the mathematical model of the heat exchanger is established by the mechanism modelling method. According to the inherent characteristics and control requirements of the heat storage system, the control schemes are proposed. The control strategies of different control algorithms, such as single-loop control, Smith predictive compensation control, cascade-Smith control, and feedforward-cascade-Smith control, are designed and adopted. The simulation model is established to obtain step response waveforms of different control systems. The advantages and disadvantages of different control strategies are comprehensively analyzed and compared. Results: After introducing the superheated steam mass-flow disturbance, the error of the single-loop control system increases. After adjusting the system to restore the oscillation state, the system error is high (10.24%). Smith predictive compensation control system fluctuates, with a peak time of 548 seconds

Resumen

The evolution of electric generation systems, according to relevant legislation, allows for the parallel evolution of the installed power capacity of renewable resources with the development of technologies for renewable resources, therefore optimizing the choice of energy mix from renewable resources by prioritizing the implementation of concentrating solar thermal plants. Thanks to their great potential, parabolic trough solar thermal power plants have become the most widely spread type of electricity generation by renewable solar energy. Nonetheless, the operation of the plant is not unique; it must be adapted to the parameters of solar radiation and market behavior for each specific location. This work focuses on the search for the optimal strategies of operation by a mathematical model of a 50 MWe parabolic trough thermal power plant with thermal storage. The analysis of the different ways of operation throughout a whole year, including model verification via a currently operating plant, provides meaningful insights into the electricity generated. Focused to work under non-regulated electricity markets to adjust this type of technology to the European directives, the presented model of optimization allows for the adaptation of the curve of generation to the network demands and market prices, rising the profitability of the power plant. Thus, related to solar resources and market price, the economic benefit derived from the electricity production improves between 5.17% and 7.79%.

Resumen

Porous silicon carbide is a promising material for ceramic receivers in next-generation concentrated solar power receivers. To investigate its tolerance to thermal shock, accelerated ageing of large coupons (50 × 50 × 5 mm) was conducted in a solar furnace to investigate the effects of thermal cycling up to 1000 °C, with gradients of up to 22 °C/mm. Non-destructive characterization by computed X-ray tomography and ultrasonic inspection could detect cracking from thermal stresses, and this informed the preparation of valid specimens for thermophysical characterization. The effect of thermal ageing on transient thermal properties, as a function of temperature, was investigated by using the light-flash method. The thermophysical properties were affected by increasing the severity of the ageing conditions; thermal diffusivity decreased by up to 10% and specific heat by up to 5%.

Resumen

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.

Resumen

Solar and Wind energy is available in plenty in the country like India.Solar power is the conversion of sunlight into electricity, either directly using photovoltaic (PV), or indirectly using concentrated solar power (CSP). Wind is the indirect form of solar energy and is always being replenished by the sun. Wind energy is the kinetic energy of air in motion also called wind.Technical potential of onshore wind energy is large. CSP technology with thermal storage having potential to replace the conventional thermal power plant.Advantage of CSP technology is that thermal storage technology is easily integrated with the CSP technology in compare with the photovoltaic and wind power technology. When the PV is hybridized with Wind it does not meet the satisfactory performance. PV and Wind power generation technologies not suitable at grid level due to intermittency in the availability of sun and wind. Hybridization of PV with CSP is the option to sole the intermittency problem and provide the energy at grid level. The research status of PV-CSP hybrid technology for its performance is summarized from the study made in this paper to provide a current global scenario, but it is observed that for economic and efficient power generation with the effective proportions of integrated PV-CSP hybrid systems that are yet to be researched.

Resumen

To solve the actual task of finding optimal generation mix and dispatch of thermal and nuclear power units, and hydro units of hydro pumped storages of Ukraine to cover day load power profile according to one of possible wind and solar generation curtailment mode the modification of mathematical MIP model is proposed. There are three modes of wind and solar generation curtailment revised in the article: 1) absolute maximum generation curtailment, 2) single for whole day decreased load factor, and 3) one per one hour decreased load factor. The possibility to allocate an exogenously determined level of frequency containment reserves (secondary reserves) on thermal power units is realized in the MIP model. The calculation’s results analysis shows that among revised wind and solar generation curtailment methods the method 2) is most appropriate in the short term because only administrative measures implementation is required, which could be put into force with appropriate legislation and does not require essential investments or implementation of complicated technical measures. The additional possible positive effect caused by the implementation of method 2) is it makes background for participation wind and solar generation in the ancillary services market and intraday balancing. In the middle term, the gradual implementation of method 3) is the most appropriate decision because a more stable power system balancing mode (minimum import/export amounts) could be provided. Moreover, extra nuclear power units and fewer coal thermal power units could be dispatched that is decreases hazard pollutions and carbon emission. The MIP model is written using MathProg language, a freeware version of AMPL. As a solver, the GNU GLPK program is used. The overall time for one calculation with standard table PC is about 30 seconds. MIP model could be used both for short-term power system optimal dispatch and for long-term national generation mix development studies under the growth rates of renewable installed capacities. Keywords: power system, daily load profile, robust decisions, mixed linear-integer problem, frequency containment reserve

Resumen

A design study was conducted to evaluate the cost-effectiveness of solar thermal power generation in a 50 kWe power plant that could be used in a remote location. The system combines a solar collector-thermal storage system utilizing a heat transfer fluid and a simple Rankine cycle power generator utilizing R123 refrigerant. Evacuated tube solar collectors heat mineral oil and supply it to a thermal storage tank. A mineral oil to refrigerant heat exchanger generates superheated refrigerant vapor, which drives a radial turbogenerator. Supplemental natural gas firing maintains a constant thermal storage temperature irregardless of solar conditions enabling the system to produce a constant 50 kWe output. A simulation was carried out to predict the performance of the system in the hottest summer day and the coldest winter day for southern California solar conditions. A rigorous economic analysis was conducted. The system offers advantages over advanced solar thermal power plants by implementing simple fixed evacuated tube collectors, which are less prone to damage in harsh desert environment. Also, backed up by fossil fuel power generation, it is possible to obtain continued operation even during low insolation sky conditions and at night, a feature that stand-alone PV systems do not offer.

Resumen

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.
