The installation of PV system aims to obtain the maximum benefit of captured solar radiation energy and to convert them into electricity. The different techniques of modeling and control of grid connected photovoltaic system with objective to help intensive penetration of solar electricity into grid have been proposed so far in different papers. The current methodologies for optimizing of generation power of PV system are not completely efficient. Therefore lot of research work is required for overall configuration of the grid connected PV system, the MPPT (Maximum Power Point Tracking) algorithm, the synchronization of the inverter and the connection to the grid. This paper focused on the grid connected photovoltaic system based on control technique of the generation power by changing of phase angle of the inverter output voltage and grid voltage. In order to synchronize an alternative current output of the PV system’s inverter into grid, the proposed method has been described, simulated by Matlab Simulink and validated by experimental results. This paper helps to give a study results about interconnection standard, power generation optimization method of PV system into power grid and their importance.
