In general, in accordance with the presence or absence of natural runoff, PSPPs are divided into two categories. One is a pure PSPP [32], where the upper reservoir has no or only a small amount of natural runoff, and the water body is recycled between two reservoirs; these PSPPs are mainly used in tasks such as peak shaving and emergency

The Nant de Drance pumped storage hydropower plant in Switzerland can store surplus energy from wind, solar, and other clean sources by pumping water
Pumped hydroelectric stations use water storage as a battery. During grid peak periods, water from an upper reservoir is released through tunnels to a lower reservoir that is either manufactured or natural, such as a river. The released water spins turbines to produce electricity. When energy demand is low, the water can be pumped back to the
