DFIG wind turbine systems are attractive renewable resources in distributed generation units and micro-grids. Due to the direct-connection of its stator windings to the single point of common coupling, DFIG is vulnerable to the unequally-distributed loads at low voltage and arises various hazardous complex dynamic behavior in reliability and harmonics. This paper studies the dynamic behavior of this system and reveals the period-doubling bifurcation phenomena. Under certain loading conditions when the system is undergoing negative sequences from unbalanced loads, the period-doubling and its stability boundaries has been observed and investigated with full-circuit MatLab simulations, illustrating the potential instability problems from loads and control parameters.
