Abstract
Renewable energy is harvested from the natural resources like sunlight, wind, tides, geothermal heat etc. These renewable energy resources can be considered to be limitless unlike the highly exhaustible conventional fossil fuels. Solar energy is one of the most important forms of renewable energy. Photovoltaic (PV) converts solar energy into electricity. This paper presents simulation of the grid-connected PV generation system under MATLAB/Simulink. The control system used is P&O algorithm based on maximum power point tracking (MPPT). It helps PV array to generate the maximum power under various operating conditions. The system is then connected to the AC utility grid by DC/AC inverter. The inverter is controlled by voltage controller and current controller. Voltage controller makes the DC link voltage constant. Current controller controls power flow for achieving the unity power factor at point of connection.
