Abstract

A great deal of research is being carried out to ameliorate the performance of grid-connected photovoltaic (PV) systems. This paper shoes the performance of a 1kW PV grid-connected system under grid failure. Among grid faults, the cases of islanding and grid voltage sags are tested with the proposed system. Hysteresis current control combined with active Islanding Detection Methods (IDMs) is developed to determine the effectiveness of the single phase full bridge inverter to detect islanding. Single Phase Induction Motor (SPIM) is taken as local load to shoes the effects of grid voltage sags with different depths and durations. A Theoretical, simulations, and experimental result shoes the performance of the proposed system.
