The integration of photovoltaic systems (PV) into the grid has raised concerns for distribution power generation systems (DPGS), including islanding fault detection. Inverter based PV system require an effective anti-islanding method. A new anti-islanding method presents for the DPGS. This method is based on introducing the harmonic component at the inverter side and phase-locked loop (PLL) based synchronization. The output reference current is modifying by each cycle by an injected signal. The disturbance caused by injected signal is small compared to other anti-islanding methods. This proposed method does not affect the zero crossing of the injected signal. The performance of the proposed method has been studied using MATLAB/Simulink.Refference:
