Active Disturbance Rejection Control for Wind Turbine Fatigue Load
Energies, 2022 With the participation of wind power in grid frequency modulation, the fatigue load of the wind turbine increases accordingly. A new control method that considers both fatigue load and output power of wind turbine (WT) is proposed in this paper. A linear
