Introduction Pumped storage power station is a kind of hydropower station with energy storage function. It uses surplus electricity during periods of low power demand to pump water from a lower reservoir to a higher one.
The pumped storage power station (PSPS) is a special power source that has flexible operation modes and multiple functions. With the rapid economic development in China, the energy demand and the peak-valley load difference of the power grid are continuing to increase.
As shown in Figure 1, in order to store energy in the form of the mechanical energy of water, an upper reservoir and a lower reservoir are necessary. Penstock is used to connect the two reservoirs. The key components of a pumped storage power station are the hydro turbine and pump, which usually adopt the form of bladed hydraulic machinery.
During the “Twelfth Five-Year Plan” and “Thirteenth Five-Year Plan” periods, to adapt to the rapid development of new energy and UHV power grids, pumped storage power stations such as Fengning in Hebei Province and Jixi in Anhui Province ushered in a new peak.
The geographical location selection for pumped storage power stations should adhere to the principle of decentralized distribution, focusing on areas near the grid load centers and regions with a high concentration of new energy sources.
Pumped storage is currently the most mature, cost-effective, and large-scale development capable green, low-carbon, clean, and flexible regulating power source for power systems .
