For now, the only energy storage technology for large-scale applications is water storage, or (i) storage of hydroelectric plant; and (ii) pump storage hydroelectric plant (PSH) [8], [9], [10]. Pumped hydroelectric systems account for 99% of the worldwide storage capacity, or about 172,000 MW [11] .

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 basic equipment of each storage power plant is a reservoir or storage basin. In the high mountains of the Alps – in valleys below a barrier structure – reservoirs form through the damming of melting snow and rainwater. In lower regions, the storage basins are usually fed by a channel from a nearby river. The dammed water shoots down ...
