Traffic-Aware Energy Management for EV Charging Aggregator Considering Spatial and Temporal Load Distribution

Considering high penetration of electric vehicle (EV), flexible charging behavior may bring great influence on power security and traffic congestion problem. In this paper, a bi-Ievel optimization is proposed to co-optimize spatial and temporal charging load distribution. In upper-level for EV charging aggregator, an energy management method is proposed for considering both the energy supply side and demand side (charging power) and decide the optimal spatial charging load distribution. In lower-level for traffic assignment problem, the equilibrium spatial load distribution is decided. The numerical analysis is provided and corresponding results illustrate the effectiveness of the proposed approach.
