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.
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).
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.
The pumped- storage power station can achieve long-term storage of large-capacity power by itself. The multiple-energy- combined pumped-storage station can also improve the quantity of new energy connecting to the power grid on the premise of guaranteeing the stability and safety of the Global Energy Interconnection 240 power grid.
The power response speed of the new pumped- storage station can reach the millisecond level, which greatly enhances the safety, reliability, and comprehensive adjustment capability of original large-scale pumped storage-power stations. Both sunlight and water resources are green and clean energy.
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.

But unlike traditional hydroelectric power plants, pumped-storage power plant does not need a lot of land for reservoirs, because it only needs to store a sufficient amount of water for design hours (usually from 6 to 20 h), minimizes impacts on the natural and ecological environment in the plant construction, with little impact on the surrounding landscape.
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
