How Can Dynamic MGs Benifit Distribution System Resilience in Hurricanes? A Quantitative Evaluation

With the development of smart grid, microgrid is considered to be an effective way to improve the resilience of distribution systems under natural disasters. Compared to fixed microgrids (FMGs), dynamic microgrids (DMGs) are more flexible and can adapt to complex scenarios after disasters. This paper first introduces the optimization models of FMGs and DMGs operation strategy. Then, a Monte Carlo-based method is proposed to systematically and quantitatively evaluate the effect of DMGs on the resilience of distribution systems, by comparing with FMGs. Finally, the proposed method is verified through a modified IEEE 37-node test system. The implementation demonstrates that the proposed method is effective in evaluating resilience of distribution system with DMGs, and it is concluded that with DMGs the distribution system is more resilient than that with FMGs
