AbstractThe need for electrical energy is increasing day by day and the required surplus electrical energy is supplied by renewable energy sources (RES). The usage of RES is a solution to save the fossil fuel reserves for the future generations to come and it also protects the environment. Solar energy as RES has number of advantages like freely available, pollution free, etc., Solar energy is converted to electrical energy using solar photovoltaic (PV) system, it has number of advantages and few challenges too. The generated voltage depends upon solar irradiation and operating temperature. Number of PV systems connected to the grid is ever increasing and this is leading to number of challenges like voltage quality, power quality, islanding etc., and these have to be increased. Solar PV system is used as distributed generator (DG). These DG’s help in supplying the additional electric power demand, improve the power quality, reduce the distribution losses, etc., This paper presents mathematical modeling of PV cell, DC/DC converter, inverter and maximum power point (MPP) controller. The discussed model is designed with Simulink block libraries and done in Matlab/Simulink software. Simulations are done and the results are deliberated and discussed.
