Ukrhydroenergo is developing the pumped storage power generation facility through a consortium, namely Research Production Association (RPA) Ukrgidroenergobud that includes Dnipro-Spetsgidroenergomontazhe, Enpaselectro, Kyivmetrobud, SHDSU, and Intergidrobud. The Dniester pumped-storage power project is located in the Chrnivtsi Province of Ukraine.
The Kyiv Pumped-Storage Power Plant ( Ukrainian: Ки́ївська гідроакумулювальна електростанція) is a pumped-storage power station on the west bank of the Kyiv Reservoir in Vyshhorod, Ukraine. The Kyiv Reservoir serves as the lower reservoir and the upper reservoir is located 70 m (230 ft) above the lower.
In addition to hydroelectric power plants (HPP) and HPS, 49 so-called small hydroelectric plants operate in Ukraine, producing more than 200 million kWh of electricity. But they have drawbacks: rapid wear of equipment, damage to the structures of a pressure fountain, drainage of reservoirs, insufficient use of means of automation and control.
In the energy sector of Ukraine, hydroelectric power plants occupy the third place after fossil fuels (coal and natural gas) and atomic energy. The total installed capacity of the Ukrainian hydroelectric power stations is currently 8% of the total capacity of the combined energy system of the country.
“DTEK was the first company to start building energy storage systems and open this market in Ukraine back in 2021. “Our priority remains unchanged: to develop green energy in Ukraine, accelerate the integration of the country’s energy system into Europe and to strengthen our country’s energy security.”

The connection interface between the accumulator and the hydraulic system can be described by two variables: the actual flow rate of the fluid entering the accumulator Qa and the fluid pressure at the accumulator inlet pa . Since the accumulator stores the hydraulic fluid by compressing the gas in it, the actual flow rate of. . Hydraulic motor/pump is an energy conversion device. It converts hydraulic energy to mechanical energy when operating in motor mode, and mechanical energy to hydraulic energy while operating in pump mode. Thus, it. . The reservoir normally has a slightly higher pressure than the minimum intake pressure of the hydraulic motor/pump to ensure proper operation.. . The generator converts the mechanical energy from the hydraulic motor to electrical energy. A Surface-Mounted Permanent Magnet Synchronous Generator (SM-PMSG) is. .

The hydraulic energy storage system enables the wind turbine to have the ability to quickly adjust the output power, effectively suppress the medium- and high-frequency components of wind power fluctuation, reduce the disturbance of the generator to the grid frequency, and improve the power quality of the generator.
Loth, Eric et al. investigated a compressed air energy storage (CAES) and hydraulic power transmission (HPT) system, as shown in Fig. 16. Compared with the system proposed by Professor Perry Y. Li, this system places the open accumulator in the tower and eliminates the air compression/expansion chamber.
For a gravity hydraulic energy storage system, the energy storage density is low and can be improved using CAES technology . As shown in Fig. 25, Berrada et al. introduced CAES equipment into a gravity hydraulic energy storage system and proposed a GCAHPTS system.
The energy in the system is stored in (E) hydraulically or pneumatically and extracted from (E) when necessary. Since hydraulic pumps/motors tend to have a higher power density than pneumatic compressors/expanders, the hydraulic path is usually used for high-power transient events, such as gusts or a sudden power demand.
For the role of energy storage systems in hydraulic wind turbine generators, the following aspects can be summarized. Hydraulic accumulators play a significant role in solving the ‘fluctuation’ of wind energy. It mainly specializes in a steady system speed, optimal power tracking, power smoothing, and frequency modulation of the power systems.
