By using power-type flywheel energy storage to assist the operation of newly built wind turbines, their frequency regulation capability can be improved. This paper proposed a virtual synchronous generator (VSG) model with flywheel energy storage and a wind turbine model and simulated the frequency characteristics of the regional power grid of these models. The results showed that the addition of the flywheel energy storage system improves the frequency regulation capability of the newly built wind turbines, enabling wind turbines to perform frequency regulation and alleviating the problem of grid frequency deterioration caused by large-scale access to wind power. Based on the simulation experiments conducted using the measured data from wind farms, compared with the traditional operating condition, the integration of a flywheelVSG system with a capacity equivalent to 10% of the wind power capacity can reduce the power grid frequency deviation by approximately 11%.
