Fuzzy positive feedback for islanding mode detection in distributed generation

This paper proposes a fuzzy voltage and frequency positive feedback (PF) for islanding detection in distributed generation system (DG). The proposed method is based on positive feedback in dq synchronous frame and the design methodology of the fuzzy detection is based on fuzzy inference rules. The main idea is to reduce the injection of disturbances at the point of common coupling (PCC) during the grid-connected operation. A comparison between the fuzzy algorithm and the classical methods are done. The simulation results demonstrate the effectiveness of the proposed approach.
