Abstract

This study proposes a comparison between two islanding detection methods (IDMs) for grid-interconnected distributed generators (DG). The first method is a passive technique based on monitoring the frequency of the system and the rate of change of frequency (ROCOF) at the point of common coupling (PCC).The second method is an active technique based on the injection of a current waveform distortion to the original reference current of the inverter, to force a frequency drift in case of islanding operation. The test results show that there is a difference between the two techniques. Islanding detection methods are investigated, simulated and evaluated in MATLAB / SIMULINK.
