Summary
With the rapid rise in electric vehicle (EV) adoption in recent years, leveraging a large number of private EVs collectively as a distributed energy storage system through vehicle-to-grid (V2G) technology has proven to be technically and economically viable for supporting smart grids. Quantifying the impact of V2G on the performance of both traffic networks and electricity grids requires robust modeling tools capable of capturing the spatiotemporal dynamics of networkwide EV travel-parking-charging-discharging activities. This talk presents a novel dynamic network equilibrium model, grounded in Nesterov’s user equilibrium principle, to accommodate departure time, route, parking, charging and discharging choices of EV commuters and characterize their behavioral response to electricity charging-discharging infrastructure, technologies, prices, incentives, and policies. As an application example of this model, this talk also discusses a time-of-use (TOU) electricity pricing problem aimed at minimizing the electricity waste from supply-demand imbalances within a citywide electricity distribution network, which embeds the dynamic equilibrium model of the city’s traffic network as its demand submodel. Overall, this model provides a network-based, behaviorally sound, computationally efficient platform for assessing and improving EV incentive and subsidy policies, V2G infrastructure deployment, and integration of transportation and electricity systems.
