Research on benefit evaluation method of pumped storage power station

The development of pumped storage power stations in China is relatively short, and there is a lack of objective evaluation of the system benefits of pumped storage power stations, which leads to the problems of inaccurate functional positioning, single investment mode, and imperfect electricity price mechanism of pumped storage power stations in China, hindering the healthy development of pumped storage power stations. In order to solve this problem, this paper establishes the benefit evaluation system of pumped storage power station, selects economic benefit, technical benefit, social benefit and environmental benefit as evaluation indexes, and constructs the benefit evaluation model based on order relation analysis and entropy weight method.
