How does a battery energy storage system work?
3.1. Battery Energy Storage System The BESS consists of an active front end (AFE), with a 30 kV A nominal power, connected to the grid and to a DC low voltage bus-bar at 600 V through a DC link supplied by a 20 kW DC/DC buck booster and a Li-Polymer battery with 70 A h and 16 kW h total capacity.
