Abstract

The increased penetration of inverter connected Distributed Generation (DG) in the utility systems demands an appropriate level of monitoring and detection mainly under islanding conditions. This paper proposes a photovoltaic (PV) system interfaced with AC distribution system incorporating islanding detection technique. The maximum power of the PV system is tracked using Maximum Power Point Tracking(MPPT) technique called Beta MPPT technique. The MPPT is achieved by varying the duty cycle of the boost converter. A three phase grid-tie inverter is used for interfacing with the grid. Under unscheduled islanding operation, the photovoltaic source will continue supplying power which causes potential risk to the line workers and user equipments. This necessitates the enforcement of a rapid and accurate islanding detection method. Inorder to detect the moment of islanding, a passive anti-islanding technique is proposed here. The feasibility of the system were verified in MATLAB/Simulink.
