Study on Strategies for Enhancing Urban Power Grid Resilience through Infrastructure Network Coupling with the Power System as the Core

To study the impact of coupling systems between urban infrastructures with the power system at the core on strategies for enhancing urban power grid resilience, this research proposed strategies for enhancing urban power grid resilience in the face of extreme event disruptions. These strategies focused on the coupling systems of the power system with communication systems, transportation systems, natural gas systems, petroleum systems, and water supply systems. The study analyzed the coupling relationships between the power system and other urban infrastructures. Based on the analysis of time scales and coupling relationships, it proposed measures to enhance urban power grid resilience. Additionally, it identified critical users of the urban power grid and established an urban power grid system analysis model. Finally, through differential strengthening of urban power grid users, the study formulated strategies to improve the resilience of the urban power grid. These strategies could provide valuable reference points for decision-makers in systematically enhancing the resilience of urban power grids.
