Grid Connected Photovoltaic System Using MATLAB/SIMULINK

Abstract

In the world, energy sources like the fossil fuels and nuclear fission are widely used for electric power generation. But burning fossil fuels like oil, coal and natural gas emits nitrogen oxide, sulphur dioxide, and mercury and other toxic metals into our atmosphere, directly causing increasing incidents of lung disease, polluting soils and waters, damaging crops. Nuclear fission produces radioactive waste, material that will remain deadly for thousands of years. So we need alternative source like renewable energy sources for electric power generation. Energy from the sun is one of the promising options option for electricity generation as it is available everywhere. In this thesis Paper, the performance of a single phase Grid connected system is studied. The system includes a PV module (1kw), a DC/DC converter and a DC/AC inverter. There are two control mechanism in the designed PV system where the first one is for maximum power point tracking of the PV module and another one is for injecting the desired amount of active and reactive power to the grid. The whole system is designed and simulated by MATLAB(simulink).
