Abstract
A method for operating a wind turbine which includes a rotor hub supporting a rotor blade includes: a) detecting changes in the aerodynamic performance of the rotor blade; b) determining a first control rule; c) determining a first power output information indicating a first power output based on the first control rule; d) changing an operational parameter and choosing a second control rule such that the first control rule is replaced by the second control rule; e) determining a second power output information indicating a second power output based on the second control rule. c) comparing the first and second power output information. If the second power output exceeds the first power output, repeating a)-f) with the second control rule being used as the first control rule in b); otherwise repeating a)-f) a different second control rule is applied in d).
