In addition to the traditional energy storage methods of wind power, hydraulic energy storage can also achieve energy storage in the process of converting wind energy to electrical energy. That is, hydraulic wind turbines can convert wind energy into other forms of energy storage and then convert other energy into electrical energy, when needed.
Battery energy storage and flywheel energy storage are mainly used for peak shaving and valley filling of system energy, which improves the quality of power generation. For the selection of the energy storage mode in a hydraulic wind turbine, when solving the problem of ‘fluctuating’ wind energy, hydraulic accumulators should still be the mainstay.
Through a case analysis, the total revenue of a traditional wind turbine equipped with a CAES system can be increased by 51%, and the total efficiency of the entire system is 74.5% within 5 days. 4. Conclusion At present, energy storage technologies applied in hydraulic wind turbines mainly focuses on hydraulic accumulators and compressed air.
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.
