Study on the Influence of Frequency Regulation Control on Load of Wind Turbine

With the increasing number of wind turbines in the power grid, the problem of frequency stability has been widely concerned. It has become a consensus in the renewable energy industry that wind turbines should have frequency regulation capability. The frequency regulation process of wind power calls active power, and the change of active power may affect the load of wind turbine. Furthermore, it will harm the reliability of wind turbines and the safety of renewable energy power systems. In this paper, a wind turbine model was built through MATLAB-Bladed co-simulation, and the influence of frequency regulation process of wind turbine on mechanical load was studied. The results showed that the effect on load of hub Mx of wind turbine by frequency regulation control is severe and should be paid more attention to.
