Abstract Resilience measures the ability of the power system to resist disturbance and quickly recover after failure. Its evaluation involves a multi-stage process of resisting, adapting, responding and recovering to disturbances. Most current researches use simulation results or statistical analysis of historical data to evaluate system resilience. This paper establishes a distribution network model based on multi-stage elastic mechanics mapping. This model fully considers the operating state and physical characteristics of the system, and conducts a multi-stage assessment of resilience from the two perspectives of resistance to disturbance and recovery after failure. It analyzes the role of soft open point (SOP) in normal operation and power supply restoration based on the elastic mechanics model. Computation and analysis conducted based on the IEEE 33-bus system and IEEE 123-node test feeder verify the rationality of the multi-stage evaluation of resilience. The influence of SOP on the resilience of the distribution network is analyzed, and the results show its effect on the improvement of resilience. The influences of different installation positions and control variables of SOP on the resilience are compared and discussed.

Key words： Resilience of power system elastic mechanics mapping soft open point equivalent elastic coefficient power restoration
