Review of wind turbine participation in grid FM

With the large-scale development of renewable energy, the renewable energy represented by wind energy is greatly integrated into the power grid, and the permeability keeps increasing. On the one hand, because the wind turbine units with small inertia time constant replace the traditional generator set, the overall inertia of the system decreases; on the other hand, the frequency characteristics of the system itself change. First, taking two-feed wind turbine as an example, we review the FM control principle research of wind power turbines, the control principle and implementation of virtual synchronizer control technology and the FM control strategy of wind power farms. Finally, future research in the field of power grid regulation is discussed
