Optimization of Energy Structure: The Role and Development Trend of Pumped Storage Power Stations in the Consumption of Renewable Energy

This paper discusses the important role of pumped storage power station (PSPS) in promoting the utilization of renewable energy. Firstly, the operating principle and advantages of PSPS are introduced, including peak load and valley filling, energy storage, frequency and phase regulation, black start and emergency backup. Secondly, it analyzes the influence of new energy and energy storage on the power grid, points out the challenges brought by the randomness, intermittency and volatility of new energy to the stable operation of the power system, and expounds the importance of the cooperation between energy storage facilities and renewable energy sources. Finally, the paper summarizes the energy efficiency and future development of PSPS, emphasizes its positive impact on augmenting the power system's flexibility, ensuring safety and reliability, and driving the adoption of renewable energy. On this basis, the future development trend is forecasted.
