Pumped Storage Hydropower | Department of Energy
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).
Design and Operation Strategy for Pumped Storage Power Plant
The head of pumped storage power station is usually set in a small range. When the water head changes in a wide range, it will lead to the reduction of turbine power efficiency and the life of hydraulic turbines.
