Abstract
This thesis presents Photovoltaic energy (PV) connected to three phase grid through back to back converter. It studies the maximum power point tracking (MPPT) for photovoltaic by two different methods.
First method is traditional one which is called incremental conductance method. In order to enhance the efficiency of tracking an intelligent method called particle swarm optimization (PSO) is used . A Back to Back converter composed of boost DC chopper and multi- level inverter (MLI) are used . Dc chopper is connected directly to the PV and is controlled to get MPPT .The MLI is used to interface with utility grid.
This Thesis deals also with the partial shading condition (PSC) phenomena which occurs most of the time .
The system is modeled and simulated by using the matlab programe. The performance of the system by using PSO shows better results compared with incremental conductance. Both of two MPPT methods feed the input of the grid tied inverter with the determined DC bus voltage.
