A novel islanding detection technique for grid connected photovoltaic system

Islanding detection is the major issue in Grid Connected Photovoltaic (PV) System and still it remains a challenge for researchers to interconnect the PV system with the Grid. The algorithms which are listed in the literature are failed to identify the Islanding phenomena for the several source configuration. In this paper a novel islanding detection technique is presented to reduce the non-detection zone (NDZ) at the point of common coupling (PCC) and it can be widely used for various renewable energy system configurations. The simulations have been carried out in Matlab/Simulink for several test conditions. The simulations results are presented to confirm the effectiveness of the proposed method.
