Power Flow Control of PV System Featuring On-Grid and Off-Grid Modes
This paper presents a PV system featuring two grid modes; on and standalone (off) mode. The main purpose of this work is verifying the effectiveness and feasibility of the power flow management strategy of the proposed system to fulfill the connected load demand with best utilization of considered sources, analyze the PV system performance under different grid modes. In case of normal grid conditions (mode ON), the PV system is connected to a three-phase grid and AC load. It supplies the load and grid in case of excess of PV power, and shares the peak load demands between grid and PV system. In case of grid faults, PV switches to off-grid mode, which it supplies the connected load and battery bank. The latter can store excess PV power or supplies the load in case of low or zero irradiances. The considered system tested using MATLAB/ Simulink.
