【 摘 要 】

This paper deals with the design of constant current controller for Photovoltaic (PV) power generator integrated with the grid. As the PV system uses the solar energy as one of the renewable energies for the electrical energy production as an enormous potential. The DC voltage generated by the PV system is boosted by DC-DC Boost converter. Maximum Power Point Tracking (MPPT) is used to track the maximum power for PV system. The utility grid is interconnected with the PV solar generator through the three phase PWM DC-AC inverter, whose control is provided by a constant current controller. This controller uses a three phase-Phase Locked Loop (PLL) to lock the grid frequency and phase. The low pass filter used to remove the high frequency ripple from the output; it seems to be efficient in supplying to load the constant voltage without phase jump. The complete mathematical model for the grid connected PV system is developed and simulated using MATLAB. The results verify that the proposed system is proficient to supply the local loads.
