DC Link-Based Integration Of PV Systems And Battery Energy Storage

Abstract

The demand for electrical power is increasing daily, which is supplied by fossil fuels, resulting in huge carbon emissions in the atmosphere. This leads electrical engineers to generate power using renewable energy sources. This paper is aimed at the simulation and development of a Solar PV system which is able to fulfil the power demand in isolated locations or a standalone condition. The system consists of various components like PV solar panel, DC-DC converter (Step up converter), and Battery storage System connected to the load. The control of the input loop of the solar PV system is shown with the help of a PI controller for maintaining the DC link constant irrespective of changes in the input side and output side parameters, resulting in a constant output. The Battery storage System is intended to make up for the deficiencies in the solar and provide uninterrupted power to the end user. The simulations are performed in the MATLAB/SIMULINK software.
