Twist correction factor for aerodynamic performance map used in wind turbine control
A method for controlling a wind turbine based on aerodynamic performance maps that account for blade twist includes controlling the wind turbine based on at least one aerodynamic performance map. Further, the method includes determining at least one speed parameter of the wind turbine. Moreover, the method includes determining a blade torsional stiffness factor. Thus, the method further includes determining, via the processor, a twist correction factor for the aerodynamic performance map as a function of the at least one speed parameter and the blade torsional stiffness factor. The method then includes applying the twist correction factor to the at least one aerodynamic performance map to obtain an adjusted aerodynamic performance map. In addition, the method includes controlling the wind turbine based on the adjusted aerodynamic performance map.
