摘　　要：高速公路是能源消耗和碳排放的重要行业,构建高速公路自洽清洁能源系统是助力实现“双碳”目标的重要手段。然而,交通负荷时空随机分布、用户充电决策的不确定性给高速公路电力-交通耦合系统的供需平衡带来挑战。拟基于流体力学与电磁场理论提出交通流“电报方程”,描述交通流在时空中的能量传播机理,克服传统分析方法无法反映电动汽车移动性的缺陷。为简化计算,借助电路理论从“场”到“路”的推演方法论,构建交通网络能路模型,并提出路阻、路感、路容等路网元件。高速公路交通能量流理论可为交通能源自洽研究奠定理论基础。Highway features high levels of energy consumption and carbon emission.Developing a novel highway energy system with self-consistent energy supply becomes significant approaches for realizing carbon peak and neutrality in China.However,the spatio-temporal random distribution of traffic loads and the uncertainty in users’charging decisions pose challenges to the supply-demand balance of highway electric-transportation coupled systems.To solve this problem,the“telegraph equation”of traffic flow based on fluid mechanics and electromagnetic field theory is proposed,which describes the spatial-temporal propagation mechanism of traffic energy flow and overcomes the defect that the traditional analysis methods can not reflect the mobility of electric vehicles.To simplify the calculation,a traffic energy circuit is constructed based on the methodology of the deduction from“field”to“circuit”in the electric circuit theory,and proposes traffic network elements such as resistance,inductor,capacitor and so on.Traffic energy flow theory of highway lays a theoretical foundation for self-consistent research of transportation-energy system.
