DESIGN OF GRID TIED BI-DIRECTIONAL INVERTER FOR BATTERY ENERGY STORAGE SYSTEM

The main aim is to develop the Energy Management Control (EMC) with proposed Bi-directional converter. The EMC consists of a towering EMC level and a small EMC level. Bi-directional Inverter is skilled of connecting a battery bank with the Buck-Boost converters (BBC) provides high DC voltage gain and power density along with grid. Battery banks are interfaced by BBC. It operates two modes: a battery discharging mode and charging modes where current is fed into the grid and current drawn from the grid respectively. The charging and discharging modes are depending upon the Battery State of Charge (SOC). The mathematical analysis and simulation studies are given to validate the proposed system.
