Abstract
This paper propose a schema of a grid connected PV control in order to provide a maximum power and high quality of current injected into the grid. Our article deals with the modeling and control of a photovoltaic chain connected to the grid. In This paper, we present the model of all the elements of the photovoltaic chain as well as the control of the different converters. The controllers used to control the inverter are conventional PI controllers. An LCL filter is used connect the inverter to the grid.
