Modeling and simulation of grid connected photovoltaic system using Matlab / Simulink

Abstract

Photovoltaic System is a huge topic that can be researched and studied on such as the arrangement of PV array is one of the issues that can be studied. Besides that, the control techniques can as well be delved into. Another important area that makes concern to the PV world would be the maximum power point tracker (MPPT) for PV to maximize the sun energy, and so many more can be said in these advanced millennia. Yet in this research work, the scope has to be scaled down in appreciation to the given time. This research project would mainly concern on the different PV technologies (amorphous silicon, polycrystalline) and their effect to the system in terms of energy output. Besides that, this project work would be designed nearly to the BIPV-PTM projects that have been implemented in Malaysia in order to verify the energy output results from the modeling and simulation activities. The project works will emphasis on Malaysia’s temperature and solar radiation. On the other hand, having so much respect to the given time, the grid connected PV system modeling may not have protection system to be included in the design and only the best inverter model would be chosen for the simulation purpose. Overall findings indicate that the modeling using MATLAB / SIMULINK can be further used for investigation and make improvement in order to identify which best technologies to be implemented. The polycrystalline PV System yields higher energy output compared to the amorphous silicon technology is another finding thru this project.
