Joint Maintenance Strategy For Urban Integrated Energy Systems Considering Distribution Network Reconfiguration Under Earthquake Disasters

Earthquake disasters could cause power outages and natural gas leaks in urban integrated energy systems, severely impacting residents' normal production and daily life. Enhancing the resilience of urban integrated energy systems can strengthen the system's ability to withstand earthquake disasters. In this paper, a joint maintenance strategy for urban integrated energy systems considering distribution network reconfiguration under earthquake disasters is proposed. The strategy analyzes the effects of distribution network topology reconfiguration on the integrated energy system, focusing on the chain reactions of faults between different subsystems. Case studies validate the effectiveness of the proposed strategy in load recovery through an urban integrated energy system composed of the IEEE-13 power system and a 7node natural gas system.
