Coordinated Operation of Coupled Transportation and Energy System based on Modified User Equilibrium Assignment Model

Electric vehicles play a vital role in reducing carbon emissions and mitigating climate change. With the aim of encouraging the adoption of electric vehicles, this paper proposes a coordinated operation model of the coupled transportation and energy system based on a modified user equilibrium assignment model. The modified user equilibrium model innovatively considers the feature of electric vehicles and the impact of charging facilities on electric vehicle flow distribution. In addition, the influence of the electric vehicle charging time and queuing time on the vehicle flow assignment is also considered. According to the flow assignment result obtained by the modified user equilibrium model, the coordinated operation model of the coupled transportation and power system is proposed to minimize the total cost. A system integrated with a power-gas coupled energy network and a 12-node transportation network coupled with 5 charging facilities is employed to illustrate the effectiveness of the proposed coordinated operation model.
