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.
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.
On one hand, introducing the energy storage system into hydraulic wind power solves the problems caused by the randomness and volatility of wind energy on achieving the unit’s own functions, such as speed control, power tracking control, power smoothing, and frequency modulation control.
It also discusses the functions of the energy storage system in terms of the stabilizing speed, optimal power tracking, power smoothing, and power system frequency modulation when generating power from hydraulic wind turbines.
Massive hydraulic storage thus offers the possibility of storing surplus electrical energy and responding reactively and with large capacities to supply and demand variability.
