Abstract

A power electronic circuit to interface small battery energy storage (BES) system with grid is proposed in this paper. BES is essential in micro grid to have power balance and stable operation when there is an intermittent power generation and demand. A single phase bilateral converter proposed here is operated as an inverter when there is no supply from grid and operated as a charging circuit to charge the BES connected at one side of the converter when there is a grid supply. Two main switching schemes are suggested and a comparison is made between them while the converter is operated in inverter mode.
