S. Chantasiriwan [85] used models of thermal power plants, parabolic trough collectors, oil-water heat exchangers, and feed water heaters to compare the power outputs obtained by integrating solar feed water heating systems into a thermal power plant. The results of a numerical analysis done on a case study of a 50-MW power plant show that the total heating

2. Introduction • Solar thermal power generation systems use mirrors to collect sunlight and produce steam by solar heat to drive turbines for generating power. • This system generates power by rotating turbines like thermal and nuclear power plants, and therefore, is suitable for large-scale power generation.
On November 29, 2005, the National Development and Reform Commission issued the "Renewable Energy Industry Development Guidance Catalog" (Fagai Energy [2005]
Solar thermal power generation is an attractive option for cost efficient renewable electricity production. In countries with high solar resources this technology is capable to produce solar electricity at below 15 €cent/kWh on a scale of 50 – 200 MWel plants.
Solar thermal power plants work like a conventional steam power plant in which the fuel is replaced by concentrated solar radiation. They use various systems of tracking mirrors to
Overall, the perspectives for the future contribution of solar energy to the global energy mix are very high, as one example the possible development of solar electricity from solar thermal power plants according to the roadmap of the International Energy Agency shown in Fig. 2, with about 11% of contribution to electricity supply.
For instance, in Germany, nearly 90% of the total solar PV power generation (26 GW) in 2012 was from solar roof power stations, whereas in China, the proportion is merely about 20%, and most of it is not connected to the grid [57]. Solar DPG, especially BIPV in China, is accepted to have great development potential. Specifically, the total architecture area that can
Naik et al. identify several barriers to solar thermal technologies in India (both for heat and power generation) and classify them in several categories. They distinguish between technology (immature and inefficient technology, unreliable, uncertain and sometimes incompatible technology and unavailability of skilled manpower), economic (high investment
The regulation capacity of concentrating solar power(CSP)plants can rival that of conventional thermal units. CSP plants can participate in peak load and frequency regulations timely and deeply, which improves the flexibility of the power system. Thus,CSP is a promising renewable energy generation technology. Based on the introduction on the
: Under the background of new energy, the complementarity of solar energy and coal-fired power plants can increase power output without increasing the thermal load of boilers and systems, which can significantly improve the operation economy of coal-fired power plants. Based on the established complementary power generation analysis model of solar thermal power station
Since the oil crisis in the early 1970s, the major developed countries in the world, such as the United States, Spain, Germany, Switzerland, France, Italy and Japan, have taken solar
Solar thermal power plants work like a conventional steam power plant in which the fuel is replaced by concentrated solar radiation. They use various systems of tracking mirrors to focus the sunlight. An integrated heat storage system enables demand-based electricity production regardless of fluctuations in the level of solar radiation
The International Energy Agency projects that solar could become the largest source of global electricity generation by 2050 under its sustainable development scenario, providing nearly 30% of worldwide electricity. Other studies suggest solar could meet the majority of energy demand in many regions with abundant sunshine and available land.

As an important form of clean energy generation that provides continuous and stable power generation and is grid-friendly, concentrated solar power (CSP) has been developing rapidly in recent years. Over the last years, the People''s Republic of China has undergone through the complex energy transition.
Since the oil crisis in the early 1970s, the major developed countries in the world, such as the United States, Spain, Germany, Switzerland, France, Italy and Japan, have taken solar thermal power generation technology as the focus of national research and development, gradually started to develop solar thermal power generation on a large scale,...
On November 29, 2005, the National Development and Reform Commission issued the "Renewable Energy Industry Development Guidance Catalog" (Fagai Energy [2005] No. 2517), which clearly developed solar thermal power generation for power grids or areas that cannot be covered by grids.

Since steam turbines can only be operated economically above a certain minimum size, today’s solar thermal power plants have rated outputs in the range of 50 to 200 megawatts. The main difference to a conventional steam power plant is the solar field, which supplies the heat for the steam generator.
Solar thermal power plants therefore rely on the storage of the intermediate product heat and not the end product electricity. Electricity is generated by means of a steam turbine cycle, which is oper-ated according to demand and is supplied from the thermal storage system.
The pipes containing the ether exposed 900 square feet of surface to the solar radiation. The water also became heated and carried the heat to the underside of the pipes, thus realizing a greater efficiency. The ether boiled and its vapor drove a small vertical, single cylinder engine.
Since solar thermal power plants can feed their electricity into the power grid even after sunset, they are of particular value for an energy system based on renewable energy sources. Solar thermal power plants are of strategic importance in sunny countries to be able to phase out coal and gas power plants in the future.
