The research on the evaluation model of the energy storage power station focuses on the cost model and economic benefit model of the energy storage power station. However, fewer studies consider the social benefits brought by the long-term operation of the energy storage power station. The cost model of energy storage power station was firstly established by considering the construction cost, storage battery rental cost, labor cost, operation and maintenance cost, disposal cost and other costs. Then, the benefit model of energy storage power station was established by comprehensively considering the economic and social benefits. Finally, the comprehensive benefit evaluation model based on the whole life cycle of the energy storage power station was established, and the optimal scale was determined by comparing the comprehensive benefits of the four scale energy storage power stations. This work helps to verify the effectiveness of the comprehensive evaluation model, and provide an intuitive comprehensive evaluation method for the selection of the construction scale of the energy storage power station.
