An orderly charging/discharging strategy for electric vehicles based on power-traffic coupling
To address spatiotemporal load imbalances and frequent overloading in distribution networks caused by large-scale electric vehicle (EV) integration, this paper proposes an orderly charging/discharging strategy leveraging power-traffic coupling. First, an electricity-transportation-society (ETS) coupling model is developed, integrating grid topology, road-network infrastructure, and transaction mechanisms. Second, the concept of user incentive threshold is introduced to enhance EV response efficiency to control signals. Building upon this, the strategy accommodates multiple charging modes (slow/fast charging) and employs bi-level particle swarm optimization (PSO) for control signal optimization: the upper layer maximizes revenues for both charging aggregators and grid operators, while the lower layer minimizes user incentive costs. Simulations results demonstrate that the strategy effectively mitigates load fluctuations, enhances renewable energy accommodation, and coordinates stakeholder interests.
