Analysis on the development prospect of solar thermal power generation
? Thirteenth Five-Year Plan? During this period, the solar thermal power generation industry in China will be in the initial stage of commercialization and large-scale construction. With the completion of the first batch of 20 solar thermal power generation demonstration projects in China, the manufacturing capacity, system integration capacity and engineering construction capacity of solar thermal power generation equipment will be continuously improved, the technical standard system will be continuously improved, the investment cost of solar thermal power generation projects will be gradually reduced, the economic benefit level will be continuously improved, and the trend of industrial development scale and commercialization will be more obvious. Under the global environment of low-carbon emission reduction, solar thermal power generation may become a new energy utilization mode in China in the future. Then, the following is the analysis of the development prospect of solar thermal power generation that I have compiled for you. Welcome to read and browse.
Status of light and heat resources in China
Solar thermal power generation requires higher normal direct solar radiation (DNI), and the direct solar radiation of the site should not be less than 65,438+700 kWh/m2a. According to the analysis of the total reserves and distribution of solar energy resources in China, the provinces that meet the requirements of solar energy resources for thermal power generation are mainly concentrated in Qinghai, Tibet, Xinjiang, Gansu, Ningxia, Inner Mongolia and other areas with good solar energy resources and large-scale land development and utilization.
Technical route of photothermal power generation
According to the different concentrating methods, the mainstream solar thermal power generation technologies mainly include tower solar thermal power generation, trough solar thermal power generation and dish solar thermal power generation technology. There is also a Fresnel solar thermal power generation technology which can be called a special case of trough technology, and its basic principle is similar to that of trough technology. At present, from the analysis of the number of solar thermal power stations that have been put into operation, under construction and planned at home and abroad, trough and tower solar thermal power generation technologies occupy the mainstream position.
Construction of Solar Thermal Power Generation Project in China
By the end of 20 15, six experimental demonstration solar thermal power stations (systems) have been built in China, with an installed capacity of 1.388 million kilowatts; 20/kloc-in September, 2006, the National Energy Administration issued the Notice on Building Solar Thermal Power Generation Demonstration Projects (Guo Neng Xin Neng [2065438+06] No.223), and determined the first batch of 20 solar thermal power generation demonstration projects, including 9 tower power stations, 7 trough power stations and 4 Fresnel power stations, with a total installed capacity of1.
Domestic related policies of solar photothermal power generation
? Twelfth Five-Year Plan? Since, the national level, the National Development and Reform Commission, the Energy Bureau and the Ministry of Science and Technology have successively issued a number of plans and policies to support the development of solar thermal power generation industry. The following table summarizes the specific policies:
Economic benefit analysis of domestic photothermal power generation projects
At present, the investment cost of thermal power plants is still high. According to different technical routes, the investment cost per kilowatt of thermal power station is about 25,000 ~ 45,000 yuan, which mainly depends on the direct solar radiation resources and capacity coefficient where the project is located, and the capacity coefficient depends on the scale of energy storage system and solar field. According to relevant research, with the expansion of installed capacity, the cost of photothermal power generation decreases according to the curve of 10%. Among them, the investment cost is mainly concentrated on the purchase of equipment. At present, the sensitive factors affecting the income of thermal power plant projects mainly include investment quota, annual power generation and on-grid electricity price.
Preliminary Work Flow of Domestic Photothermal Power Generation Project
To invest in a photothermal power generation project, first of all, it is necessary to conduct site selection inspection in the early stage of the project to determine whether there are conditions that affect the development of the project and whether the project has basic development value. Secondly, the feasibility study of the project should be carried out, and the solar energy resources should be analyzed in detail by compiling the feasibility study report to accurately calculate the power generation. At present, the filing system is adopted for the establishment of photothermal power generation projects in Gansu, Inner Mongolia and Qinghai provinces.
