Claim 0:
1. 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, and
wherein according to the icing criteria, icing is expected depending on a temporal change of at least one of the weather parameters
wherein evaluating if icing of the rotor blades is expected includes, for an icing area, defining an area in which icing is expected, wherein the area is determined with respect to a parameter space spanned at least by:
the determined ambient temperature, and
the determined relative humidity,

wherein the icing area is determined further depending on the wind speed, and
wherein evaluating if icing of the rotor blades is expected depends on determining whether the determined ambient temperature and the determined relative humidity define a weather point inside the icing area.
