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.
Among these, the hydraulic energy storage component (HESC) is crucial to the entire HER system, as it directly influences energy utilization efficiency [27, 28, 29]. Therefore, effectively utilizing HESCs is essential for optimizing HER system performance [30, 31]. A hydraulic accumulator is the primary HESC used in the HER system.
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.
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.
Electrical recovery strategies utilize batteries or supercapacitors for energy storage, aligning with the trend toward electrification. Electro-hydraulic hybrid systems integrate hydraulic and
