Coordinated Post-Disaster Recovery and Assessment Method for Integrated Electricity-Gas-Transportation System

Extreme disasters may cause damage to energy system’s components and transportation networks. How to achieve a rapid restoration of power supply is crucial. A coordinated post-disaster recovery and assessment method for the integrated electricity-gas-transportation system is proposed in this paper, and a repair sequence assessment model for the damaged road in transportation network based on topology and operational metrics is also established. Then, considering the dynamic changeability of the transportation network status, a rolling-updated model for dynamic road restoration and repair crew scheduling is proposed. Finally, we propose the coordinated post-disaster recovery and assessment model of electricity-gas-transportation system, in which the modified alternating direction multiplier of method is applied to solve. The impact of the transportation network repair process on system load recovery under different perspectives is verified by arithmetic examples.
