In operations, hydropower stations utilize their own reservoir storage to redistribute uneven inflows over periods of years, months, weeks, days or hours, thereby controlling when and how much electricity is generated. This ability enables them to quickly respond to the increasing demand for flexible power in electrical grids 2, 3.
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.
Among them, hydropower and pump stations are used as flexible resources. Facing the uncertainty of the power output of WPP, the hydropower station needs to determine its power generation process according to the output process of WPP, and the pump station needs to consume excess electricity when the power output of WPP is larger.
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.
