摘要

This paper presents a bi-objective and bi-hierarchical coordinated optimization model for integrated urban traffic system (UTS) and power distribution system (PDS). The two objectives target the least traffic congestion in UTS and the lowest power losses in PDS. In the upper hierarchy, the two objectives are co-optimized with traffic light settings as optimized variables. In the lower hierarchy, a vehicle re-routing process includes a dynamic vehicle assignment and a dynamic microscopic simulation for all individual vehicles. The two challenging issues, that is, the coordination between the microscopic simulation and the relatively macroscopic modeling and the spatiotemporal optimizations in both UTS and PDS, are fully resolved. The coordinated optimization model is solved using the NSGA-II algorithm which is suitable for multiple objective problems. The effectiveness of the proposed model and algorithms is verified using an example of integrated UTS and PDS.
