The newly proposed reclosing scheme is based on mechanical DCCBs for structural reuse, with an active signal injection branch added. Since the fault current is restrained by the current limiting reactor installed at the outlet of an MMC, quick isolation of faults is not a must. Thus, mechanical DCCBs can find their usage in DC networks [6].

Conventional reclosing schemes do not consider a synchronism problem between the utility and the BESS when reclosing is attempted. Due to the existence of both sources at the sending and receiving ends, a reclosing in distribution systems with BESS is very similar to reclosing in a transmission line, and thus the synchronism problem …
