Scenario construction and vulnerability mitigation of natural hazards-triggered power grid incidents

In this study, we focus on understanding of the comprehensive impact of natural disasters on urban power grids by expanding the conventional definition of vulnerability to a broader context. Our work introduces the Power grid Incident Cause-Effect (PICE) model as a novel framework for analyzing the scenarios under which power grids are affected by various natural hazards. By analyzing 20 emblematic cases of power grid failures caused by major natural disasters, including extreme heat, typhoons, earthquakes, heavy rainfall, ice storms, lightning, floods, and wildfires, we delineate a timeline of vulnerability capabilities. This timeline spans from active prevention through adaptive response to dynamic recovery, offering insights into mitigating the vulnerability of power grids.
