As more distributed generators join the utility grid, the concern of unintentional islanding increases. This concern is due to the safety hazards this phenomena imposes on the personnel and equipment. Passive anti-islanding methods monitor grid parameters to detect islanding, whereas active methods inject perturbation into current waveform to drive theses parameters out of limit. The performance of...
The active islanding detection methods (IDMs) can effectively mitigate the islanding non-detection zones (NDZs) compared with passive IDMs in the inverter based DG systems but the improvement depends highly on the interface control schemes. In this paper, different reactive power variation based IDMs, including Active Frequency Drift method (AFD), Slip Mode Frequency Shift Method (SMS) and Sandia...
