摘　　要：为了应对交通清洁能源高效利用的重大需求,建立适配交通用能特征的高速公路自洽能源系统,对“电源”(源)、“电网”(网)、“负荷”(荷)、“储能”(储)四大组成要素进行了分析,提出了基于“源-网-荷-储”的高速公路自洽能源系统架构。依据系统所处地理位置、电网等级、自然禀赋、负荷等级以及当地政策,将高速公路自洽能源系统的运行策略分为全额并网,自发自用、余电上网,自发自用、余电储能,离网运行4种模式,进而得到不同场景下高速公路自洽能源系统规划的一般路径。在此基础上,围绕高速公路自洽能源系统规划中的基于多态清洁能源自然禀赋的供给潜力评估、公路用能负荷预测、储能方式选择及配置比例、系统运行效能评价4个关键问题进行了探讨。研究结果表明:合理规划高速公路自洽能源系统不仅促进电力能源与绿色交通的融合发展,同时对降低交通运营成本、提高清洁能源利用率具有重大意义。In order to meet the increase demand of efficient utilization of clean energy for transportation,a self-consistent energy system for expressway was established.The components of highway self-consistent energy system,power source,grid,load and energy storage were analyzed,and the architecture based on the components was proposed.According to the geographical location of the system,grid level,natural resources,load level and local policies,the operation strategy of the highway self-consistent energy system can be divided into four modes,full grid connection,self-use and surplus power online,self-use and surplus power storage,off-grid operation.Then the general path of the highway self-consistent energy system planning in different modes was proposed.Furthermore,four key issues in the highway self-consistent energy system planning were discussed,including the evaluation of supply potential based on natural resources,the forecast of highway energy load,the selection of energy storage mode and capacity allocation,the operation efficiency evaluation of system.The results show that reasonable planning of highway self-consistent energy system not only promotes the integration of electric energy and green transportation,but also reduces the traffic operating cost and improves the utilization rate of clean energy.7 tabs,14 figs,37 refs.
