Feasibility of pumped storage power station

What are the environmental benefits of a pumped storage power station?

Environmental Benefits The pumped storage power station uses water to generate electricity and store energy, and there is almost no emission of pollutants.

What is a pumped storage power station?

Like a savings bank for electrical energy, a pumped storage power station typically has two storage modes [ 31 ]. The first one is integral storage and usage, which uses the power grid to reduce excess power when the requirement is low.

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 can Abandoned-Mine pumped storage technology improve the power grid?

Abandoned-mine pumped storage technology can help the peak shifting of the power grid and improve the operating stability and economy of the power grid, but the construction of the pumped storage power station is restricted by geographic conditions; that is, there must be a large enough drop between the upper and lower reservoirs.

How long does a pumped storage power station last?

According to the spirit of the relevant documents of the national power grid on charging by time periods, the time for the continuous power generation of the pumped storage power station is determined as: 07:00~15:00 for a total of 8 h, and the remaining time periods are pumping periods with a duration of about 16 h.

Can abandoned mines be used for pumped storage power stations?

The unique features of abandoned mines offer considerable potential for the construction of large-scale pumped storage power stations. Several countries have reported the conversion of abandoned mines to pumped storage plants, and a pilot project for the conversion of an underground reservoir group has been formalized in China.
