交通-能源融合下智能网联道路供电弹性：挑战、提升策略与展望

The connected and automated highway technology has become key technology for improving traffic efficiency and ensuring traffic safety. The connected and automated highway system enables real-time information exchange between vehicles and roadside infrastructure, enhancing the intelligence level of traffic management. However, the reliable operation of the connected and automated highway system depends on continuous and stable power supply. The frequent occurrence of extreme events poses a serious threat to the power supply system of connected and automated highway. In the context of transportation-energy integration, the necessity of resilience enhancement and the vulnerability of the connected and automated highway power supply system in extreme events are firstly analyzed. Secondly, the bidirectional positive feedback between power supply system resilience and the reliability of connected and automated highway system applications is clarified and the cascading failure/recovery effects of the connected and automated highway power supply system in extreme events are elaborated. Then, based on the characteristics of the connected and automated highway system under transportation-energy integration, existing methods for enhancing power system resilience are analyzed and summarized, and pre-disaster prevention, in-disaster mitigation, and post-disaster recovery measures are further proposed for coordinated resilience enhancement of both the power supply system and applications of connected and automated highway system. Finally, from the perspectives of the transportation-power co-simulation of the connected and automated highway, cross-system coordination of diverse and flexible resources as well as the utilization of high-entropy energy in road areas, future resilience enhancement strategies for the power supply system of connected and automated highway are explored.
