Abstract: The participation of electric vehicle（EV） users in local energy sharing of charging stations can not only meet the demand for energy sharing of charging stations, but also bring benefits to participants by optimizing the allocation of local energy resources.Considering that the high entry threshold and transaction cost of the traditional electricity market restrict local energy sharing,taking into account the response characteristics of EV users, a real-time energy sharing mechanism for charging stations based on price consistency is put forward. First, considering the influencing factors of driving behaviors for EV users, including road congestion, pre-sharing electricity price, distribution locational marginal price, and charging and discharging cost utility parameters of EVs, an EV user selection model is established. Then, based on the dual problem of the social welfare maximization model in the centralized dispatch mode, a real-time energy sharing mechanism based on price consistency is deduced in the local energy sharing network. The mechanism takes the sharing electricity price as a consistent variable, and the participants achieve the price identity through information exchange, thus maximizing the social welfare of energy sharing. Finally, the simulation is carried out in the coupling system including the road network, power grid and energy sharing network. The simulation results show that the road travel time and pre-sharing electricity price have the greatest impact on the choice behavior of EV users. The participation of EV users with high charging efficiency and low discharging cost in the energy sharing of charging stations can improve both the individual and overall economic benefits.
