Pumped energy storage system technology and its AC–DC

The basic operation principle of a pumped-storage plant is that it converts electrical energy from a grid-interconnected system to hydraulic potential energy (so-called ''charging'') by pumping the water from a lower reservoir to an upper one during the off-peak periods, and then converts it back (''discharging'') by exploiting the available hydraulic potential
