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.

Thermal energy storage is mainly divided into molten salt and hot water energy storage [34]. Because it is cheap, not limited by materials, and relatively safe to operate, hot water energy storage technology is now relatively mature and widely used. Extensive research has been conducted on hot water energy storage.

Electrical energy may be stored through pumped-storage hydroelectricity, in which large amounts of water are pumped to an upper level, to be reconverted to electrical energy using a
When energy demand rises, stored water from the upper reservoir is released into the lower reservoir by flowing through a hydro-electric power station which produces energy. There are two types of PSH: open-loop, when one of the reservoirs is connected to a naturally flowing water source; and closed-loop, when none of the reservoirs are connected to an

With the large-scale access of renewable energy to the grid, the load rejection of pumped storage power stations (PSPSs) has become increasingly frequent, thus increasing the possibility of runaway accidents.
As the most mature and cost-effective energy storage technology available today, pumped storage power stations utilize excess WPP to pump water from a lower reservoir (LR) to an upper reservoir (UR).
This method stores energy in the form of water, pumped from a lower elevation reservoir to a higher elevation. In pumped hydroelectric energy storage systems, water is pumped to a higher elevation and then released and gravity-fed through a turbine that generates electricity.
The construction of pumped storage power stations among cascade reservoirs can improve the flexible adjustment ability of the clean energy base, which also changes the water transfer and electrical connection of UR and LR at the same time.
Hence, to support the high-quality power supply, this research explores the complementary characteristics of the clean energy base building different types of pumped storage power stations, and recognizes the efficient operation intervals of the giant cascade reservoir.
The construction of pumped storage power stations among cascade reservoirs is a feasible way to expand the flexible resources of the multi-energy complementary clean energy base. However, this way makes the hydraulic and electrical connections of the upper and lower reservoirs more complicated, which brings more uncertainty to the power generation.
The energy storage in gigawatt-hours (GWh) is the capacity to store energy, determined by the size of the upper reservoir, the elevation difference, and the generation efficiency.
