With China continuously scaling up the construction of integrated clean energy bases like “hydro-wind-storage” and new energy bases such as “Shagohuang”, pumped storage stations, especially variable-speed ones, will be more widely applied as energy storage support in regional grids (China Power, 2023).
To promote the construction of pumped storage power stations, it is of great significance for the construction and optimization of modern power systems. 2. Development trends of pumped storage energy in China To effectively support the construction and development of pumped storage power stations, China has issued a series of supporting policies.
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.
Hubei Energy Group Co., Ltd., Three Gorges Construction Group Before the 14th Five-Year Plan, the development of pumped storage power stations in China was mainly carried out by power grid enterprises, namely State Grid Corporation and China Southern Power Grid Corporation.
Through the characteristics analysis of the new type of pumped-storage power station, three types of optimal station locations are proposed, namely, the load concentration area, new energy concentration area, and ultra- high-voltage direct current receiver area.
The PSPS is the best tool for energy storage. The pumped storage has the function of energy reserve, and it solves the problem of electricity production and consumption at the same time, and not easy to store. Thus, it can effectively regulate the dynamic balance of the power systems in electricity generation and utilization.
