Abstract

Abstract: The economic benefits of pumped storage power plants can be effectively assessed by measuring the investment benefits of conventional pumped storage projects that take into account the needs of regional power grids and new energy sources to maintain power supply. Firstly, a large-scale conventional pumped storage power plant in operation is fully investigated, and based on the actual data, its operation conditions are introduced, its operation characteristics in different seasons are analyzed, and the participation of the power plant in the electricity market is introduced.Secondly, the initial investment cost, the operation cost, and various types of income of the pumped storage power plant are measured, and the economic indicators of the system under different utilization hours are analyzed.Finally, based on the measured data, the social and economic benefits of the calculations are further studied from the dimensions of power supply protection benefits, new energy consumption benefits, etc. The results show that the pumped storage power plant has excellent operational benefits and social benefits, which can provide a certain reference for the actual pumped storage investment calculations and economic benefits calculations.

Key words: pumped storage, operational characteristics, investment benefit, new energy consumption, cost and expense
