In these recent times, where the renewable energies are the new trend and the sustainable energies are starting to play a big role in the society in order to eliminate the dependence on the fossil fuels, funding a way to collect these clean energies and to convert them into electricity at their highest performance is without any doubt essential. Nevertheless, the way to link the power generator from these renewable resources to the main grid is significant. The present work studies step by step the design, modelling, control and simulation based on photovoltaic (PV) system, and it is integrated to the utility grid with the help of power electronic converters. This work can be carried out using many software. MATLAB/SIMULINK will be used for design, control and analysis in this project owing to its user-friendly characteristics. Modelling of the equivalent circuit model to simulate the working principle of PV cell is studied in detail and a Maximum Power Point Tracking (MPPT) control algorithm to force the PV system works as its highest operating point is applied. A large battery unit is employed to meet the critical loads in the absence of PV power and the utility grid. This unit is integrated to the grid with the usage of DC-DC converter. In this analysis, it would result in a constant grid voltage which has a reliable continuous power without any significant repercussions. And the PV and the battery will supply the load and the remaining power is fed back to the grid.
