A Comprehensive Approach for Minimizing Post-Disaster Interruption Costs in Smart Grids

This paper addresses the complex interplay between power systems and unpredictable natural forces, emphasizing the vulnerability of essential lifeline facilities to rare disasters and deliberate attacks. The focus is on distribution system restoration, crucial for power grid resilience. A literature review reveals a gap in existing studies, with many overlooking the communication interdependency in restoration processes. Despite a few papers considering this interdependency, the cost of interruption is often neglected. This work presents a two-layer smart grid model during natural disasters, incorporating power-communication interdependency. The unique contribution lies in including the cost of interruption, demonstrating a saving of 57% in overall interruption cost. The paper employs a systematic modeling approach, validated against existing results, offering insights into optimized restoration sequences.
