Abstract: Resource evaluation is an important basis for resource development. In order to quantitatively evaluate the resource endowment of pumped - storage sites in China and reveal the distribution law of pumped - storage site resources, a statistical analysis method was used. Based on the data of 452 pumped - storage projects, a quantitative evaluation method for the zoning and classification of pumped - storage site resource endowments was proposed from two dimensions: geographical zoning and administrative zoning, with the static investment per kilowatt as the index, to quantitatively evaluate the site resource endowments. The research found that, on the one hand, the resource endowment of pumped - storage is highly related to topographic, geological and water source conditions; on the other hand, zoning evaluation of pumped - storage resources with the prefecture - level administrative region as the granularity is representative in terms of data and feasible in terms of operation. The research results quantitatively evaluate the resource endowments of pumped - storage sites in different regions, which can be used to classify and guide the site selection and development of pumped - storage power stations. The evaluation method and its results are of great significance for supporting the establishment and improvement of the benchmark capacity electricity price of pumped - storage, helping to further improve the two - part electricity price mechanism, promoting cost reduction and efficiency increase in the industry, facilitating the green and low - carbon transformation of the power system, and achieving the "double carbon" goal.
