Coordinated Post-Disaster Restoration for Coupled Distribution-Transportation System

Effective coordination of diverse resources for rapid post-disaster recovery is crucial for ensuring power grid security. Urban power grids encompass varied load categories, and the recovery process is closely interconnected with transportation networks. To comprehensively address these challenges, this paper proposes a collaborative post-disaster recovery approach for urban coupled distribution-microgrid-transportation systems considering tiered load demands. First, differentiated electricity load demand characteristics are analyzed leveraging Long Short-Term Memory-AdaBoost (LSTM-AdaBoost) model, enabling precise identification of post-disaster priority user demand. Then the post-disaster model for coupled system is established incorporating the dispatch of repair crews within the transportation network and the support role of microgrids. The optimization problem is addressed by Benders decomposition technique. Numerical results demonstrate the effectiveness of the proposed post-disaster collaborative recovery and solution approach in accelerating power supply restoration.
