A wind turbine comprising: a rotor having a plurality of blades; and a controller. The controller is arranged to independently control each of the plurality of blades and/or one or more components of each blade in order to increase a driving moment of each blade independently of other of the blades when speed of wind acting on the wind turbine is below rated. The controller is also additionally or alternatively arranged to independently control each of the plurality of blades and/or one or more components of each blade independently of other of the blades when wind force acting on the blades is above cut-out in order to reduce a mechanical load experienced by at least a part of the wind turbine.
