How about building a pumped storage power station

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).

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.

Why is pumped Energy Storage important?

Besides, it is an effective power storing tool and now it has become the largest and most widely used energy storage form. Many countries configured a certain proportion of pumped storage power in the network to keep their grid stability.

What is the structure of a power station?

The structure of a pumped storage power plant includes an upper reservoir and a lower reservoir, which form the first potential energy. The virtual constant pressure pool and the low-pressure pool constitute the second potential energy. The hydraulic transmission mechanism is composed of a number of components, including a turbine, a generator, and a pump.

Does pumped storage power maintain grid stability?

Many countries configured a certain proportion of pumped storage power in the network to keep their grid stability. This paper introduces the current development status of the pumped storage power (PSP) station in some different countries based on their own economic demands and network characteristics.

How to increase water head variation in pumped storage power station?

In order to increase the variation of water head in the design of a pumped storage power station, a pumped storage power station using a virtual constant pressure tank is proposed in this paper. The limitation of the range of water head change can result in wasted reservoir capacity and limit daily power generation.
