Pumped storage hydropower (PSH) is a type of hydroelectric energy storage. It is a configuration of two water reservoirs at different elevations that can generate power as water moves down from one to the other (discharge), passing through a turbine. The system also requires power as it pumps water back into the upper reservoir (recharge).

Pumped Storage Hydropower. High efficiency in energy storage and release, especially during peak electricity demand. Higher capital cost due to construction of reservoirs and dams, but cost-effective in long-term energy management. Potential impact on ecosystems and water flow, but generally lower than fossil fuels.

The basic principle of PHES is to utilize attitude intercept to store electric energy. The plant pumps water in a reservoir in low-price periods, working as a load,

The principle behind the operation of pumped storage power plants is both simple and ingenious. Their special feature: They are an energy store and a hydroelectric power plant in one. If there is a surplus of power in the grid, the pumped storage power station switches to pumping mode – an electric motor drives the pump turbines, which pumps

6. Anhui Jixi PSH Station. With a total installed capacity of 1,800 MW, Anhui Jixi PSH Station has six units with a single unit capacity of 300 MW and a rated head of 600 m. The project''s units are the first self-developed pumped-storage units with high head (600-700 m) and high speed (500 r/min) to be put into operation in China.

Pumped storage power station can play the role of peak-shaving frequency modulation, accident reserve, black start power supply and so on. It is an effective means to ensure the safe operation of

This study assesses the efficiency of the empirically recommended supported design of the underground powerhouse of the Panlong pumped-storage power station in Chongqing, China by using 3D distinct element code (3DEC). Field and laboratory tests were conducted to investigate the geological properties of intact rock and rock

The vegetation change monitoring of engineering construction project usually adopts manual investigation, which is difficult to timely monitor the change. The pumped storage power station project is often constructed in mountain area, which will damage natural resources and arises soil erosion. In order to timely analyse vegetation change caused by pumped
