Autonomous Microgrid Restoration Using Grid-Forming Inverters and Smart Circuit Breakers
The proliferation of distributed inverter-based resources (IBRs) raises the questions if these IBRs can be used to blackstart microgrids and distribution feeders after major outages. In this paper, we propose and evaluate an autonomous microgrid restoration concept using grid-for...
