1. A method comprising:
setting a pitch angle of a rotor blade of a rotor of a wind turbine, wherein the rotor blade is configured to move rotationally about a rotor blade longitudinal axis for setting the pitch angle by a pitch drive, wherein the setting comprises:
determining an aerodynamic power of the rotor;
establishing a nominal pitch angle as a function of the aerodynamic power; and
setting the pitch angle to the established nominal pitch angle,
wherein the nominal pitch angle is established based on an aerodynamic power factor depicted in a portionally linear control function, wherein portions of the portionally linear control function are defined by the aerodynamic power, and the aerodynamic power factor is a power-dependent additional blade angle.
