Modeling of Grid-connected Solar Photovoltaic Energy Generation System

This paper coversthe design and modelling of a grid-connected solar photovoltaic energy generation system. Solar-PV system with MPPT (maximum power point tracking) controller to track maximum power point is designed with a dc-dc converter. The output of PV array is fed to the VSI converter through a dc-dc converter. For regulating the output voltage and current under varying conditions,a VSI is designed with closed loop controllers. Simulation model for this designed system is developed in Simulink/Matlab platform and simulated results are presented to demonstrate its performance under steady and dynamic conditions.
