Abstract The microgrid fault current is bidirectional, and a key issue of its protection is how to determine the fault direction. The analysis of positive-sequence additional network of microgrid shows that the applicability of the positive-sequence fault component (PFSC) based directional element in gird-connected microgrid is decided by the quadrant of the PSFC impedance angle of inverter interfaced distributed generator (IIDG). However, due to the diversity of IIDG power output strategy and the uncertainty of voltage variation at the IIDG coupling point, the quadrant of PSFC impedance angle of IIDG cannot be determined. In this regard, this paper proposed a multi-stage IIDG fault control method. By manipulating the fault response characteristic of IIDG in a specific time window, the PSFC impedance angle was controlled to a given value, so as to construct a PSFC feature independent of IIDG power output strategy in microgrid. The Simulink simulation results verified the accuracy of the microgrid fault direction identification by adopting the proposed IIDG fault control method.
