The basic criteria for this kind of energy storage unit installations include, (a) the existence of an autonomous power system with local power stations, (b) the high electricity production cost,
Hydropower is the largest dispatchable renewable power source. In operations, hydropower stations utilize their own reservoir storage to redistribute uneven inflows over

Pumped storage hydropower (PSH) is a form of clean energy storage that is ideal for electricity grid reliability and stability. PSH complements wind and solar by storing the excess electricity they create and providing the backup for when the wind isn’t blowing, and the sun isn’t shining.
The joint operation of wind, solar, water, and thermal power based on pumped storage power stations is not only a supplement and improvement to traditional energy systems but also a crucial step towards a cleaner, more efficient, and more sustainable energy future.
Penstock is used to connect the two reservoirs. The key components of a pumped storage power station are the hydro turbine and pump, which usually adopt the form of bladed hydraulic machinery. The mechanical energy of the water and the mechanical energy of the runner can be converted to each other.
In operations, hydropower stations utilize their own reservoir storage to redistribute uneven inflows over periods of years, months, weeks, days or hours, thereby controlling when and how much electricity is generated. This ability enables them to quickly respond to the increasing demand for flexible power in electrical grids 2, 3.
