Research on development demand and potential of pumped storage power plants combined with abandoned mines
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
