Design and simulation of utility grid connected PV system with battery storage

Abstract

Currently, extensive research is being conducted to reduce CO2 emissions stemming from fossil fuel resources. One promising solution is the utilization of renewable energy sources such as photovoltaic and wind power. This project aims to integrate a photovoltaic (PV) array into the utility grid, coupled with a storage element.To achieve this goal, a Matlab/Simulink model is developed and simulated to optimize the PV system’s power output. Subsequently, a suitable power conditioning system is selected to convert the DC output voltage into a 50Hz AC voltage, meeting the required distribution levels for interfacing with the utility. The control system for this power conditioning setup is also carefully chosen. It is crucial that the designed topology maintains a high power factor.In conclusion, the obtained results are thoroughly discussed and interpreted to assess the effectiveness of the integrated PV array and storage system within the utility grid.
