This article mainly reviews the energy storage technology used in hydraulic wind power and summarizes the energy transmission and reuse principles of hydraulic accumulators, compressed air energy storage and flywheel energy storage technologies, combined with hydraulic wind turbines.
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.
Hydraulic storage is significant because it fulfills a variety of roles in reinforcing renewable energy sources (RES) for services with different timeframes of operability: instantaneous, daily, or seasonally. These storage options are not only essential for developing multiple renewable energy sources, but also for ensuring continuity of supply and increasing energy autonomy.
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.
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.
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.
