Today, direct control strategies are more and more demanded in high dynamic performances, since they offer superior dynamic response. One of the major concerns in these methodologies is the estimation of rotor flux which plays an important role in conventional rotor flux position-based direct power control (DPC) methods. Recently there have been more interests on stator flux position-based DPC and different direct control strategies are accordingly developed. The aim of this paper is thus to analyse the dynamic behaviour and robustness of rotor flux position- and stator flux position-based DPC methods for a DFIG-based wind system under the same operating conditions and to develop a comparative study based on the simulation results.
