A wind turbine (30) comprising: a rotor (36) having a plurality of blades (38); and a controller (100). The controller (100) is arranged to independently control each of the plurality of blades (38) and/or one or more components of each blade (38) in order to increase a driving moment of each blade (38) independently of other of the blades (38) when speed of wind acting on the wind turbine (30) is below rated. The controller (100) is also additionally or alternatively arranged to independently control each of the plurality of blades (38) and/or one or more components of each blade (38) independently of other of the blades (38) when wind force acting on the blades (38) is above cut-out in order to reduce a mechanical load experienced by at least a part of the wind turbine (30).
