IMPLEMENTATION OF PHOTOVOLTAIC CELL AND ANALYSIS OF DIFFERENT GRID CONNECTION

Abstract

This report focuses on best modelling of a photovoltaic cell by making it closed loop. This model is based on mathematical equations and is described through an equivalent circuit including a photocurrent source, a diode, a series resistor and a shunt resistor. The developed model allows the prediction of PV cell behaviour under different physical and environmental parameters. The model can also be used to extract the physical parameters for a given solar PV cell as a function of temperature and solar radiation. In addition, this study outlines the working principle of PV module as well as PV array. In order to validate the developed model. The PV model is connected into different grid systems and analysed the performance of different systems. The comparative study also made in accordance with ripple output voltage by using the result analysis dc grid connection and two stage ac grid connection is made closed loop for the best performance.
