Reclosing scheme using synchronism checking for utilization of BESS in distribution system

This paper proposes a reclosing scheme using synchronism checking for utilization of battery energy storage system(BESS) in a distribution system. The algorithm disconnects the faulty phase and keeps the power supply from the BESS to the healthy phase. Synchronism checking between the main source side and the load side is applied to minimize the transients at the reclosing instant.The BESS at the faulty phase is reconnected after checking the successful reclosing. The distribution system including BESS and proposed reclosing scheme are modeled by the electromagnetic transients program(EMTP)/ATPDraw.The various simulations by varing the fault clearing time are conducted and the simulation results are discussed.Also, the relation between proposed reclosing scheme and reliability is discussed.
