Toward a resilient distribution system

Resiliency with respect to extreme events, such as a major hurricane, is considered one of the key features of smart distribution systems by the U.S. Department of Energy (DOE). In this paper, approaches to resilient distribution systems are reviewed and analyzed. Three important measures to enhance resiliency, i.e., utilization of microgrids, distribution automation (DA), and vulnerability analysis, are discussed. A 4-feeder 1069-node test system with microgrids is simulated to demonstrate the feasibility of these measures.
