Can pumped storage power stations be built among Cascade reservoirs?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.
Can pumped storage power stations support a high-quality power supply?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.
How do pumped storage power stations work?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).
How pumped storage power stations can improve Ur and LR?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.
Can pumped storage power stations reduce peaking pressure?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.
