Abstract

A method for determining a wind sector distribution comprising a plurality of wind sectors WS_n, with n = 1, ..., N, for the operation of a wind turbine (100) a wind turbine (100) and a control system (200) are specified, the method comprising the steps (S1, S2) of providing wind condition information (I_wc) representative of average wind conditions at the location of the wind turbine (100), and performing an optimization routine (OR) for maximizing an estimated annual energy production AEP of the wind turbine (100) based on the wind condition information (I_wc) and the plurality of wind sectors WS_n, wherein the optimization routine (OR) comprises determining the plurality of wind sectors WS_n, wherein for each wind sector WS_n an effective turbulence intensity I_eff_n, based on the wind condition information and an admissible turbulence intensity I_design_n, is determined, wherein each of the admissible turbulence intensities I_design_n corresponds to a specific power mode and is based on a plurality of design parameters of the wind turbine (100), a turbulence intensity ratio TIR_n = I_eff_n/I_design_n is determined for each of the wind sectors WS_n, and the optimization routine is performed with the constraint that a weighted combination of the turbulence intensity ratio TIR_n of all wind sectors WS_n is equal to or less than 1.
