Description
Summary:This paper presents a Predictive Direct Power Control Applied to the Doubly Fed Induction Generator operating with or without voltage dip, in variable speed operation. The predictive controller is obtained from state-space DFIG model. The control law is derived by optimization of a cost function that considers the difference between the predicted outputs - stator active and reactive powers - and their references. It used a discrete state-space model to describe the system. As the voltage dip is not predicted, it is considered to be a disturbance in the control algorithm. Digital simulations are performed to verify the efficiency potential of the proposed controller.
