Technology: Pumped Hydroelectric Energy Storage
Summary of the storage process Pumped storage plants are a combination of energy storage and power plant. They utilise the elevation difference between an upper and a lower storage
Pumped storage hydropower (PSH) is a type of hydroelectric energy storage. It is a configuration of two water reservoirs at different elevations that can generate power as water moves down from one to the other (discharge), passing through a turbine. The system also requires power as it pumps water back into the upper reservoir (recharge).
Penstock is used to connect the two reservoirs. The key components of a pumped storage power station are the hydro turbine and pump, which usually adopt the form of bladed hydraulic machinery. The mechanical energy of the water and the mechanical energy of the runner can be converted to each other.
As shown in Figure 1, in order to store energy in the form of the mechanical energy of water, an upper reservoir and a lower reservoir are necessary. Penstock is used to connect the two reservoirs. The key components of a pumped storage power station are the hydro turbine and pump, which usually adopt the form of bladed hydraulic machinery.
Pumped storage hydropower plants fall into two categories: Pure (or closed-loop) pumped storage: in this type of plant, naturally flowing sources of water into the upper reservoir contribute less than 5% of the volume of water that passes through the turbines annually.
