This paper studies how to mitigate the blade root flap-wise moment of wind turbine under the influence of wind shear and tower shadow effect. An individual pitch control strategy based on simplex method is proposed to mitigate the blade root flap-wise moment and its 1p component load on the basis of ensuring the power control of the wind turbine. This method and the individual pitch control strategy of conventional PI control are applied to a 4.5 MW wind turbine model, and simulation is carried out under turbulent wind conditions to compare and analyze the blade root flap-wise moment, its power spectral density and the output power. The analysis of the simulation operation data of the 4.5 MW wind turbine model shows that, the individual pitch control strategy based on the simplex method can effectively mitigate the blade root flap-wise moment and its 1p component, and stabilize the output power.
