The aim of designing wind turbine blades is to improve the power capture ability. Since rotor control technology is cur-rently limited to controlling rotational speed and blade pitch, an increasing concern has been given to morphing blades. In this paper, a simplified morphing blade is introduced, which has a linear twist distribution along the span and a shape that can be controlled by adjusting the twist of the blade’s root and tip. To evaluate the performance of wind turbine blades, a numerical code based on the blade element mo-mentum theory is developed and validated. The blade of the NREL Phase VI wind turbine is taken as a reference blade and has a fixed pitch. The optimization problems associ-ated with the control of the morphing blade and a blade with pitch control are formulated. The optimal results show that the morphing blade gives better results than the blade wit
