Abstract In order to develop the operation performance of the overall DFIG generation system, taking into account the GSC’s auxiliary control, a coordinated control strategy with the direct resonant regulation has been presented in this paper. The selected electromagnetic quantities according to the target are used as the controlled variables for the resonant regulator in the positive synchronous reference frame so as to approach the commanded voltages. As a result, the rotor and GSC currents can be regulated without sequential separations and reference calculations. Besides, the proposed method can enhance the adaptability to generator parameters variations. Simulated and experiment results demonstrate the availability of the proposed direct resonant control methods for grid- and rotor-side converter.
