Enhancing Distribution System Resilience by Dynamic Post-Disruption Microgrid Formation

다국어 초록 (Multilingual Abstract)

The post-disruption microgrid (MG) formation is an operational measure proposed to boost distribution system resilience against disastrous events. This paper proposes a two-stage post-disruption MG formation strategy. The first stage optimizes the MG topology to be formed and the second stage transforms the faulted distribution system into the desirable MGs. Mathematically, an optimal MG topology determination model is formulated to flexibly allocate distributed generators and critical loads into multiple MGs with the objective of maximizing load pickup. The second-stage problem is then triggered to search for a secure switching sequence that satisfies frequency dynamics limitations. The performance of the proposed model is verified in a modified real-world 136-node test feeder with loss of the substation.
