What is Pumped Storage Hydropower? 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 ...
To generate electricity when power from the plant is needed, water flows from the upper reservoir, because of gravity, through turbine (s) that rotate generator (s) to produce electricity. The water then flows into the lower reservoir where it remains until electricity demand lowers. When this occurs, the turbines spin backward to pump the ...
Although large-scale energy storage directly in the network is difficult, pumped storage hydropower plants (PSHPs) have made this process possible indirectly. In fact, the main purpose of the coordinated PSHPs operation is to store the excess electric energy of the system during off-peak hours and use this energy at peak load hours [5,6].
A pumped storage plant uses hydro technology to store energy generated by other power stations. Storage is achieved by pumping water from a lower to an upper reservoir. The stored energy can then be recovered by running the hydro units in reverse as
