Claim 0:
1. A method of controlling a wind turbine, the wind turbine comprising a hub having at least one blade comprising at least one first add-on member and at least one second add-on member, wherein the at least one first add-on member is closer to an inboard portion of the blade than the at least one second add-on member, the at least one first add-on member and the at least one second add-on member being actuated to alter aerodynamic properties of the blade, the method comprising:
acquiring a target noise level; and
controlling the at least one add-on member of the blade such that an actual noise level caused by the operation of the wind turbine is equal to or below the target noise level;
wherein the first add-on member is controlled in a different manner compared with the second add-on member, the first add-on member being controlled to achieve a first noise reduction level and the second add-on member is controlled to achieve a second noise reduction level, further wherein first noise reduction level is lower than the second noise reduction level.
