Abstract: With the frequency and intensity of extreme natural disasters significantly increasing, the reliability standards of traditional power systems are no longer sufficient to withstand the impact of “black swan” events.Power grid resilience is not merely a matter of structural strength, but rather a dynamic response capability interwoven with robustness, redundancy, resourcefulness, and rapiditiy. Based on the resilience triangle theory and the emergency management lifecycle theory, this paper systematically elaborates on a strategic framework for enhancing urban power grid resilience across the pre-disaster prevention, in-disaster response, and post-disaster recovery phases.In the era of smart grids, the power grid must transition from traditional passive defense to a form that possesses proactivity and self-healing capabilities, thereby providing a solid energy foundation for the construction of resilient cities.
