Claim:
A method for operating a wind farm with a plurality of wind turbines, comprising: adjusting operating parameters of the wind turbines during operation of the wind farm according to an optimization goal, wherein the optimization goal is a maximum value of a total output of the wind farm produced from a sum of all individual outputs of the wind turbines, wherein the optimization goal is given by an optimization of wind speed ratios of the wind turbines, a wind speed ratio of a respective wind turbine being given by a ratio of a central wind speed immediately downstream of the respective wind turbine to a central wind speed immediately upstream of the respective wind turbine, wherein the wind speed ratio of the respective wind turbine is adjusted using an angle of inclination of rotor blades of the respective wind turbine, and wherein the optimization of wind speed ratios of the wind turbines is determined according to the following equation: { q i } opt = arg ⁢ ⁢ max ⁡ ( ∑ i = 1 N ⁢ P i ⁡ ( q i ❘ v i ) ) wherein N is the number of wind turbines in a row and the wind turbines in a row are numbered in ascending order in the wind direction, wherein q i is the ratio of the central wind speed immediately downstream of the i-th wind turbine to the central wind speed v i immediately upstream of the i-th wind turbine, and wherein P i (q i |v i ) is the individual output of the i-th wind turbine as a function of the wind speed ratio q i in the case of a given central wind speed v i immediately upstream of the i-th wind turbine.
