The need for both proactive and reactive operating procedures that ensure resilient operation of the electricity network is evident from the impact of the recent high-impact, low-probability (HILP) events. This work presents a novel framework for the assessment, quantification, enabling, and enhancement of overhead power distribution network (OPDN) resilience considering the participation of mobile microgrid (MM). Two unique physical system metrics specific to overhead networks are used in conjunction with the topological metrics for resilience assessment. The quantification of resilience involves diamond pairwise comparison, Choquet integral, and kth-order additive fuzzy measure that allow accurate representation of the network operator opinion in weighing various metrics and factors of the resiliency. Resilience-enabling and enhancement algorithms for preventive response and operational contingency scenarios are outlined in this work. An operational resiliency enhancement algorithm that decides the location of the MM based on the outcomes of the resiliency framework is proposed. The framework aids the resilient operation of the OPDN during HILP events by reconfiguring the network with a suitable feasible network considering the participation of MM. The proposed techniques are tested through simulation studies considering the field data of a 415V OPDN in Kolkata, India.
