Compared with traditional PSPP and open pit pumped storage, the reservoir capacity depends on the volume of underground water storage space, so it is difficult for a single mine to build a large-scale energy storage power station.

Pumped storage power stations usually arrange galleries in the backfill area at the bottom of the reservoir basin. Under the influence of uneven deformation, the galleries may be difficult the load to adapt to deformation and generate cracking, which can affect dam safety. In this study, the upper reservoir of Hohhot pumped storage power station was taken as a case study.

Abstract: The pumped storage power plant is reliable and flexible, with the ability to adapt swiftly to load changes. When the storage station was previously operational, the load distribution between units did not always take into account the differences in operation characteristics between the units, which resulted in higher energy consumption during operation. For this The operating strategy of fixed-speed generating units is the same as that of the current Hohhot Pumped Storage Power Station: “From 0:00 to 7:00 (00:00~07:00), all units is operated in pump The Hohhot Pumped Storage Power Station, also known by Huhehaote, is located 20 kilometres north of Hohhot in Inner Mongolia, China.

Abstract: The power house in Inner Mongolia Hohhot Pumped-Storage Power Station is underground. In case of sudden increase of water inflow or failure of drainage system, the accident of flooded power house will happen.

The hydropower station consists of a super-high arch dam (height 289 m), spillway tunnels, and two large underground power stations. The dam crest is about 709 m long and is divided into 30 transverse joints with a total affecting the success rate of of 31 dam monoliths. The influence of the pumped storage power station life cycle costs on comprehensive benefits is analyzed quantitative, and case analysis validates the effectiveness of the proposed method.

The turbines generate clean electrical energy, contributing to a total installed capacity of 28,000 kilowatts and an annual power generation of 6.16 million kilowatt-hours. Hohhot’s new energy landscape is expanding further with plans for the China Electric Power Energy Storage Independent Shared Energy Storage Station and other 关键词: 抽水蓄能, 双层优化, 削峰填谷, 负荷分配 Abstract: The pumped storage power plant is reliable and flexible, with the ability to adapt swiftly to load changes.
