Claim 12:
13. A method for controlling heating of rotor blades of an aerodynamic rotor of a wind turbine, the method comprising:
evaluating if icing of the rotor blades is expected, wherein evaluating if icing of the rotor blades is expected is based on an icing criteria that includes a determined ambient temperature, a determined relative humidity, and a determined wind speed, and
initiating heating the rotor blades if icing of the rotor blades is expected,
wherein each of the determined ambient temperature, the determined relative humidity, and the determined wind speed define a weather parameter,
wherein according to the icing criteria, icing is expected depending on a temporal change of at least one of the weather parameters,
wherein initiating heating the rotor blades occurs in a heating time interval, and
wherein if icing is expected, heating is initiated depending on an expected produced power expected to be produced by the turbine during the heating time interval.
