Abstract In this paper, a modified predictive direct power control(P-DPC) strategy is presented for doubly fed induction generators(DFIGs). The basic principles of the conventional P-DPC are expounded for DFIGs. A serious drawback of the conventional P-DPC is that the predicted time duration for the active voltage vectors may be less than zero, resulting in significant low order current harmonics. Based on a deep study on the causes to this phenomenon, a modified time duration predicting strategy is proposed. A comparative study by numerical simulation and experimental testing of the modified P-DPC, conventional P-DPC, vector control and look-up table direct power control (LUT-DPC) shows that the modified P-DPC strategy presents much better steady-state and transient performance in comparison with the conventional P-DPC with reduced low-order harmonic currents while it can still maintain the inherent merits of excellent dynamic performance of the conventional LUT-DPC.
