摘要
【目的】为在电动汽车快速发展背景下响应其呈现的多元化充电需求,研究了多类型充电桩协同的充电站规划方法。【方法】首先,从电动汽车、交通网和电网的角度,基于图论的思想,建立了车-路-网耦合下的充电站选址定容规划方法;然后详细表征了电动汽车车主的选桩特性,选取慢速充电桩(slow charging post,SCP)、快速充电桩(fast charging post,FCP)、移动充电桩(mobile charging Post,MCP)和超级快速充电桩(ultra-fast charging post,UCP)作为规划的主要设施,以年化社会总成本最小为目标,建立了含多类充电桩和多条件场景约束的充电站规划模型;再基于条件场景变换和二阶锥松弛方法将规划问题转化为混合整数二阶锥规划问题,并通过Gurobi求解器进行求解;最后,仿真结果验证了所提模型的高效益和有效性。【结果】结果表明,充分考虑SCP、FCP、UCP和MCP的规划结果最优,且MCP的引入有效发挥了充电需求高峰的应急作用,减少了17.82%的规划成本。【结论】所构建的充电站规划模型中,电动汽车车主能够在多类型充电桩中按照一定原则进行选桩,且多类型充电桩的协同配置比单一类型充电桩的规划配置更具有灵活性,能够在满足充电需求的条件下节省年化社会总成本。
[Objective]In response to the increasingly diversified charging demands arising from the rapid development of electric vehicles(EVs),this study investigates a planning method for charging stations based on the collaboration of multiple types of charging posts.[Methods]From the perspective of EVs,transportation networks,and power grids,a siting and sizing planning method for charging stations under vehicle-road-grid coupling is first established based on the graph theory.The charging behavior characteristics of EV users are then explicitly modeled,and four types of charging posts are selected as the main facilities:slow charging post(SCP),fast charging post(FCP),mobile charging post(MCP),and ultrafast charging post(UCP).A planning model is constructed with the objective of minimizing the annualized total social cost,incorporating constraints from multiple scenario conditions and multiple charging post types.The planning problem is then reformulated as a mixed-integer second-order cone programming(MISOCP)problem via scenario transformation and the second-order cone relaxation techniques and solved using the Gurobi optimizer.[Results]The simulation results demonstrated the high efficiency and effectiveness of the proposed model.The results indicated that the planning solution considering SCP,FCP,UCP,and MCP was optimal.Notably,the integration of MCPs provided an effective emergency response during peak charging demand periods and reduced the overall planning cost by 17.82%.[Conclusions]In the proposed planning model,EV users can select among multiple types of charging posts based on specific principles.The coordinated configuration of diverse charging posts offers greater flexibility than single-type configurations,enabling the satisfaction of charging demands while reducing the annualized total social cost.
