Power ripple reduction of DPC DFIG drive using ann controller

Anotace: Over the past years, many kinds of control strategies is proposed for doubly fed induction generators drives. Among them, direct power control (DPC) has gained more importance due to simple control structures and fast dynamic response. However, it has a disadvantage of high ripples in active power, reactive power, and slow response because of hysteresis controllers in active and reactive. To improve the performance of DPC and to reduce the active and reactive powers ripples, DPC based artificial neural network (ANN) controller is proposed in this work. The simulation is carried out using Matlab/Simulink and compares the proportional-integral (PI) controller and in DTC artificial neural is implemented and simulated results are shown.
