Application for built pumped storage power station

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 a pumped storage power station be built in China?

Combined with the underground space and surface water resources of the Shitai Mine in Anhui, China, a plan for the construction of a pumped storage power station was proposed.

How is a pumped storage power station constructed?

A pumped storage power station is constructed by utilizing the difference in heights between the abandoned open pits. Since the upper and lower reservoirs are completely exposed to the surface, it is also called open abandoned-mine pumped storage ( Figure 3 ).

How does a pumped storage pump station work?

The pumped storage pump station uses the excess power of wind-PV plants, and the water in LR connected to the pump station is pumped to UR. The excess power of non-storable WPP is transformed into the gravitational potential energy of storable water.

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 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.
