Summary: This paper introduces a new differential protection scheme for inverter-based islanded microgrids (IBIMGs) based on the signed correlation technique. The scheme is formulated based on the signs of the instantaneous phase currents, and signed correlation index and fault detection index are defined to measure and discriminate different fault situations. Simulation results demonstrate that the proposed scheme operates correctly in various fault scenarios.

Summary: A differential protection scheme based on fundamental frequency superimposed current phasors is proposed for microgrid feeders in this paper. The scheme uses dq components instead of conventional Fourier algorithms to extract phasors. Simulations in MATLAB/SIMULINK software are carried out to test the performance of the proposed method for different fault scenarios. The results confirm that internal faults are detected in a few milliseconds, while the scheme remains insensitive to external faults with CT saturation and other system disturbances. The proposed scheme is unaffected by the microgrid mode of operation, direction of power flow, and DG type.
