DC distribution system integrated BESS for commercial building applications

In this paper, DC distribution system for building including BESS is composed, and integrated operation is proposed by using the system. Control method of power conversion device is proposed by reference from upper level MCU(Micro Controller Unit). Especially, when parallel operation of BESS, control method is proposed, which is maintain same voltage, and put out different current. Simulation result is given for verification has proposed configuration of system and method of operation in this paper. Through simulation result, proposed configuration and operation methods are verified.
