Pumped-storage plants are used for storing energy during periods of low energy demand and generating electricity during periods of high energy demand. They are usually known to have short storage cycles of days or weeks, however, they can also be used to store large amounts of water, as well as energy.
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
