The following conclusions can be condensed. (1) It is unreasonable to directly apply the equations from the design code [23] to the cases of downstream surge tanks in a pumped-storage power station. (2) For a pumped-storage power station with a high-head, the regulations from the Japanese empirical equations are reasonable.
Pumped storage power stations In water scarce areas, pumped storage schemes are used as an alternative to conventional hydroelectric power stations to provide the power needed during peak periods. Instead of the water being discharged, it is retained in the system and re-used.

A sketch of the hybrid power plant under consideration is given in Fig. 1 a. The plant consists of a wind farm and a pumped-storage unit, which absorbs almost the entire wind production to elevate water from the reference level of a lower reservoir and store it to an upper reservoir of equal capacity, at +430 m static head.A number of wind generators of equal size …
The PHES having installed capacity from a few hundred kW to more than 10 MW are generally known as big plants, although there is no official definition of large hydroelectric power stations. A small pumped hydroelectric energy storage may have a capacity of up to 10 MW maximum, but again, there is no such standard definition or very clear cut ...
1 Introduction. In the context of global energy structure transformation, pumped storage power plants play a crucial role in the power system (Zhang et al., 2024a).As renewable energies such as wind and solar power become more widely used, the balance between supply and demand in the power system faces unprecedented challenges (Jia et al., 2024).With their …

High-frequency pressure pulsations are hydraulic phenomena that are frequently observed in pumped storage power stations. These pulsations can propagate through the steel pipes, concrete lining, and the surrounding rock system, which in turn may have detrimental effects on the environment, such as noise pollution, and relocation of the local residents.
