Energy Management of PV – Battery Based Microgrid System

Abstract

This paper deals with the management of Energy Storage System (ESS) connected in a microgrid with a PV array and regulate the battery charge, hold and discharge operations using DC-DC bidirectional converter based on the requirement of the Load. The PV array along with the battery and load is simulated for various conditions such as PV supplying and charging the battery, PV supplying only the load, battery supplying the load and PV-Battery both supplying the load. The output parameters like voltage, current and power graphs are plotted and analysed for each condition. The entire paper is simulated on Matlab-Simulink environment.
