Abstract

Supplying and sharing power with grid has become one of the most wanted photovoltaic applications (PV). Moreover, PV based inverter and DC to DC converters are getting more attention in recent days mainly in remote areas where connection to the grid is technically not possible. Power generation by Photovoltaic is free and reliable. This paper presents the novel technique for maximum-power point tracking based on perturb and observe algorithm of photovoltaic (PV) energy conversion system. In order to obtain the maximum power extracted from the PV array, usually two parameters are considered, namely solar irradiation and temperature, most of the research work has been carried out by considering these two parameters. The proposed technique gives optimum utilization of PV array and enhances the applications of PV systems for both stand alone and grid connected systems. The study has been carried out in the MATLAB-Simulink environment. And also validation of the simulated results with the theoretical results shows proper matching. The results obtained from the simulation of the system are very much satisfactory. It is found that PV fed inverter system is working better.
