Summary:A method 100 for controlling a wind turbine 10 based on aerodynamic performance maps that account for blade twist includes controlling 102 the wind turbine based on at least one aerodynamic performance map. Further, the method includes determining 104 at least one speed parameter of the wind turbine 10. Moreover, the method 100 includes determining 106 a blade torsional stiffness factor. Thus, the method 100 further includes determining 108, 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 100 then includes applying 110 the twist correction factor to the at least one aerodynamic performance map to obtain an adjusted aerodynamic performance map. In addition, the method 100 includes controlling 112 the wind turbine 10 based on the adjusted aerodynamic performance map.
