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 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.
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).
Considering the change of the intra-day load demand can reduce the peaking pressure of the power receiving end. More research on the economics of the pumped storage power station can be carried out when the relevant mechanisms of China's new power market are further improved.
Further, the key reservoir with multi-year regulation ability plays a very important role in the comprehensive utilization efficiency of the whole cascade reservoir, and it is vital to determine its reasonable operating water level and comprehensive utilization flow according to different working conditions in different seasons.
