With the rapid development of new power systems, peak regulation capacity has become a key factor in ensuring the stability of power supply. As an important peak regulation method, pumped storage power plants can effectively balance the load fluctuations of the power grid and optimize the energy use efficiency. In new power systems, pumped storage power plants can not only improve the peak regulation capacity of the power grid but also provide effective support for the integration of renewable energy. This paper analyzes the role of pumped storage power plants in the peak regulation process and explores their application prospects and economic performance in new power systems. Pumped storage power plants have high peak regulation efficiency and show good economic returns. In the future, with the progress of technology and policy support, pumped storage power plants will play a more important role in new power systems.
