提出了一种基于层次分析法和渗流理论的配电系统弹性评估方法。使用该度量，可以进行定量分析以分析可能的控制决策的影响，从而主动地使具有多个微电网和其他资源的配电系统的弹性操作成为可能。开发的弹性度量也可以用于短期配电系统规划。能够量化弹性的好处可以帮助配电系统规划工程师和运营商证明控制动作的合理性，比较不同的重新配置算法，并制定主动控制动作，以避免由于即将发生的灾难性天气情况或其他不利事件而导致的电力系统停电。使用修改后的CERTS微电网和修改后的工业配电系统所提出的方法进行验证。仿真结果表明，考虑电力系统特性的拓扑和复合度量，以量化的配电系统的弹性与所提出的方法，和弹性的改善，使用两阶段重构算法和多个微电网。
This paper presents a method for quantifying and enabling the resiliency of a power distribution system using analytical hierarchical process and percolation theory. Using this metric, quantitative analysis can be done to analyze the impact of possible control decisions to pro-actively enable the resilient operation of distribution system with multiple microgrids and other resources. Developed resiliency metric can also be used in short term distribution system planning. The benefits of being able to quantify resiliency can help distribution system planning engineers and operators to justify control actions, compare different reconfiguration algorithms, and develop proactive control actions to avert power system outage due to impending catastrophic weather situations or other adverse events. Validation of the proposed method is done using modified CERTS microgrids and a modified industrial distribution system. Simulation results show topological and composite metric considering power system characteristics to quantify the resiliency of a distribution system with the proposed methodology, and improvements in resiliency using two-stage reconfiguration algorithm and multiple microgrids.
