Abstract

Islanding detection based on wavelet and S-transform approach is presented in this paper in distributed generation (DG) based hybrid power system. The hybrid system consisting of photovoltaic (PV), fuel cell (FC) and wind energy systems (WES) connected to utility grid are considered. Further, coherency properties between the energy resources are studied to analyze the impact of islanding on the hybrid system. Simulation results clearly reflect the advantages of S-transform in localizing and detecting the islanding of different resources over wavelet transform.
