However, wind power generation is greatly affected by the environment, so that the output electric energy quality is poor, the randomness is strong, the prediction accuracy is low, when the wind speed in the external environment changes randomly, the output power of the wind turbine also fluctuates, and the randomness and the fluctuation bring great challenges to the electric energy quality and stability.

In addition, although the high-frequency power of the fan can be stabilized through an external energy storage link, because of the limitation of the charge and discharge period of the energy storage system, the service life of the energy storage system is influenced by adopting the energy storage to absorb the high-frequency power, the replacement frequency of the energy storage system is increased, and the system cost is greatly increased. Therefore, the fan control system needs to be optimally designed, so that the unit does not respond to the wind speed of high-frequency change, and the output power does not contain high-frequency power caused by tracking the fast-changing wind speed, thereby better meeting the energy consumption requirement of the electrolytic tank.
