Abstract

The paper focuses on developing the control for directly connected battery energy storage system (BESS) in low voltage direct current (LVDC) distribution systems. The main purpose of the control is to provide essential connection/disconnection and charge/discharge functions. Additionally, due to direct connection, it is necessary to implement control functions for management of the power flows in the distribution network. Furthermore, the control system is capable of running the system as island and seamlessly disconnecting and reconnecting to the feeding medium voltage (MV) network. Control system enables implementation of the Smart Grid (SG) functionalities and practically eliminates the interruptions seen by the electricity end-users.
