Abstract

The paper presents a control technique of a photovoltaic power system connected the Power grid. The electric system includes a PV module, a DC/DC converter and a DC/AC converter to release the grid connection. A maximum-power-point-tracking (MPPT) technique is used to drive the DC/DC converter and a hysteresis technique is used to drive the DC/AC converter. These techniques ensure the PV optimum Power extraction. Matlab/Simulink environment and ISIS simulator are used to implement the system. From intensive simulation the system is tested and his accuracy is validated.
