This paper describes the islanding phenomenon on Grid-Connected Photovoltaic (PV) Arrays for developing new techniques for islanding detection. A novel islanding prevention scheme is presented. It consists in monitoring the dc-link voltage of Voltage Source Converter (VSC). This Anti-Islanding (AI) method is validated by directly comparing the islanding detection time in various scenarios with the detection time offered by the rate of change of frequency (ROCOF) technique.
