Pumped-storage hydroelectricity (PSH), or pumped hydroelectric energy storage (PHES), is a type of hydroelectric energy storage used by electric power systems for load balancing. A PSH system stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation.
The height (h3) can be minimized up to 0.5m by means of installing unit-vortex beam, as illustrated in Figure 7.8.1-5, according to the “Hydraulic design of Intake/Outlet for pumped storage power station, No.161 Electric Power Civil Engineering, July 1979, Japan”.

Controlled Release: The operation of dams in these systems is all about control. Releasing water from the upper reservoir through turbines generates power. This process is crucial during peak electricity demand periods. Design Efficiency: The design of dams in pumped storage systems is tailored to maximise energy storage and generation efficiency.
This research underscores the criticality of dams in PSH systems for efficient energy storage and sustainable power generation (3). Controlled Release: The operation of dams in these systems is all about control. Releasing water from the upper reservoir through turbines generates power.
The largest dams in Russia are the Sayano-Shushenskaya Dam, which has an installed capacity of 6,400 MW; the Krasnoyarsk Dam (6,000 MW); the Bratsk Dam (4,500 MW); the Ust-Ilimsk Dam (4,320 MW) and the Zeya Dam (1,330 MW). Some of the most recent dam projects are the Bureya Dam (2010 MW) and the Irganai Dam (800 MW).
