英文摘要：

Concentrating solar power （CSP） technology is one of the major technologies for converting solar energy to electricity. As an output controllable energy supply system, it will take the base-load and peak load of large scale renewable energy system in the future. The global total CSP installation reached 4 GW at the end of 2014, and most of the CSP stations have been concentrated in Spain and the United States. New CSP components and systems are coming to commercial maturity. New markets are emerging on most continents where the sun is strong and sky is clear enough, including China, India, the Middle East, North Africa, and South Africa. The International Energy Agency （lEA） roadmap research result shows that the percentage of solar thermal electricity （STE） production in global electricity is to reach 11% by 2050. The main factors affecting solar thermal power development include solar direct normal irradiance （DNI）, topography, water resource, and local grid infrastructure, etc. The macroscopic site selection of CSP station in China has been calculated based on the GIS platform, and the results show that the exploration reserves of CSP is more than 1400 GW. China has more than 40 years＇ research experience in CSP technology. There are more than 500 enterprises engaged in the field of solar thermal power related research and manufacturing, and several experimental CSP demonstration stations and high temperature solar systems which were constructed and operated in the past decade. But there are still no large scale commercial CSP stations, because of the lack of feed-in tariff. The distributed CSP technology is employed close to the user side, combining thermal storage, multi-energy mix, and cascade use of electrical-thermal-cold energy. It will promote the wider application of large ratio distributed electrical-thermal-cold renewable energy system which is secure and stable. This technology can improve the integrated energy efficiency of the CSP system and reduce costs. There are still several
