Abstract
A wind turbine includes at least one blade having a pressure side, a suction side, a leading edge, and a trailing edge that define an airfoil-shaped profile. The suction side and/or the pressure side has a morphable region. The wind turbine also includes a control system configured to activate the morphable region to alter the airfoil-shaped profile and reduce negative lift generated by the blade when the blade is oriented at a negative lift angle.
