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.
Hence, construction of pumped storage power stations can effectively improve the flexibility of the clean energy base and support the depth of new energy consumption .
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 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.
Pumped storage power stations (PSPS) can be divided into the pure pumped-storage power station (PPSPS) and the hybrid pumped-storage power station (HPSPS) according to the presence or absence of runoff inflow in UR and LR.
In the HWPHS, the HWPPHS and the HWPRPHS, the proportion of WPP in the transmission channel decreases successively, which indicates that electricity generated by WPP is indirectly converted into hydropower by the pumped storage pump station.
