A Mathlab-based simulation of PV-System integrated into a grid

Abstract

This project presents a simulation model of the electric part of a grid connected photovoltaic generator. The model contains a detailed representation of the main components of the system that are the solar array, Buck converter and the grid side inverter. A proper control of the DC/DC converter is developed in order to extract the maximum amount from the photovoltaic generator. The grid interface inverter transfers the energy drawn from the PV module into the grid by keeping common dc voltage constant. Modeling and control is carried out using the causal informational graph method. The simulation results under Matlab/Simulink show the control performance and dynamic behavior of grid connected photovoltaic system.
