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.
The benefits of energy storage technologies (ESTs) as a step of managing the future energy demand, by considering the case of electric power systems (EPS) in arid regions, were the focus of this study.
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.
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.
Environmental Benefits The pumped storage power station uses water to generate electricity and store energy, and there is almost no emission of pollutants.
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.
