A Simple and Powerful Model Predictive Direct Power Control for DFIG

In this paper, a proposed Finite Control Set (FCS) Model Predictive Controller (MPC) is designed to the power of the grid and rotor sides converters to improve the performance of the Doubly-Fed Induction Generators (DFIGs). The FCS-MPC is implemented to regulate the stator active and reactive powers of DFIG and the DC-link voltage, minimizing the error between them and their references. Simulations and laboratory experiments were performed, showing results for a 0.56 kW DFIG. Finally, it was verified that the proposed system can maintain the stator power and DC-link voltage at a reference, with no significant torque oscillations.
