Abstract
Pumped storage is the main regulating power supply of power system. It is more urgent to build a new power system with new energy as the main body. In order to accelerate the development of pumped storage projects, it is urgent to improve the economic evaluation method of pumped storage projects under the background of new power system construction. Firstly, the value of pumped storage in ensuring the safety and reliability of the new power system, improving the utilization level of renewable energy, and improving the performance of power generation, distribution and consumption of the new power system is analyzed. Then, the economic evaluation model of pumped storage project is optimized, and an index system covering value contribution to the new power system, financial profitability and anti risk ability is constructed. Finally, through the comparative analysis of pumped storage and coal-fired power generation projects, the scientificity and rationality of the model are verified.
