摘　　要：交通是重要的能源消费部门。随着电动汽车、天然气汽车等清洁能源车辆的快速发展,交通系统与电力系统、天然气系统等能源供给网络的耦合逐步增强。面向日渐融合的能源网和交通网,该文考虑电动汽车、天然气汽车与城市综合能源系统的耦合,提出并建立城市综合能源系统优化规划模型,协调充电站、加气站等能源设施与城市电网、天然气管网的扩建。首先基于交通流量和路网结构,对电动汽车、天然气汽车的能量补给需求进行了分析与建模,并建立了能量补给设施的建设约束。其次,以全系统投资和运行费用最低为目标,考虑电网、天然气网运行约束,构建了优化规划模型,设计了相应的求解算法。最后,以西安市交通网为基础构造算例验证了模型和方法的有效性。结果表明,统筹考虑交通系统和能源系统特性,进行协调规划是必要的,并且能够在显著降低城市综合能源系统规划成本的同时提高运行效率;忽略协同作用会导致电力和天然气网络的线路拥堵。Transportation system is an important energy consumption sector.With rapid development of alternative fuel vehicles(AFVs)including electric vehicles(EVs)and natural gas vehicles(GVs),the coupling has been greatly enhanced among transportation,power,gas and other energy supply networks.Considering the emerging energy and transportation systems,this paper incorporates the coupling among EV,GV and energy systems,and proposes an optimal planning model and method for urban integrated energy systems to coordinate the expansion of energy infrastructure and AFV refueling station.First,based on the road network and traffic flow constraints,the refueling demand of AFVs is analyzed and the constraints for refueling stations are obtained.Second,the optimal integrated planning model is developed with energy system operation constraints and the solution method is provided.Finally,the case studies based on a real-world urban network verify the validity and feasibility of the proposed model and method.The results show that the coordinated planning is necessary and can improve the operation efficiency while reducing the investment cost.Ignoring the synergy may cause congestion of power lines and gas pipelines.
