摘要

•DC distribution systems may suffer problems in protection selectivity.•Voltage source converter (VSC) protection can be obtained using a suitable control.•Coordination between VSC, dc feeders protections and storage devices is presented.•This methodology, experimentally validated, ensures selectivity and security.
