Direct power control of a DFIG fed by a two level inverter using SVM algorithm

In this paper, a direct power control (DPC) is applied to a doubly fed induction generator (DFIG) based wind energy. The space vector modulation (SVM) algorithm has a constant switching frequency compared with the classical control; this advantage offers a good total harmonic distortion (THD) rate of the generated currents, reduces the oscillations of the calculated powers and makes the system more robust against significant disturbances. Combined with the direct power control, the system behavior will present a fast response time, which will guarantee a good tracking of the reference signal. The enhanced performances brought by this strategy are studied in the simulation results.
