摘　　要：交通枢纽是能源消耗的重要场所,为有效降低其系统运行成本和减少碳排放,在分析交通枢纽自然资源禀赋和冷热电气等多种负荷并存特点的基础上,构建交通枢纽冷电综合能源系统优化调度模型,以降低系统运行成本。首先,构建含有新能源发电和储冷装置的冷电综合能源系统架构,建立系统内制冷机、蓄冰池等单元的数学模型,为后续优化调度提供基础。其次,在考虑能源供应与能源转化约束、能源存储设备出力约束以及系统运行约束的基础上,以降低系统运行成本为目标,构建系统优化调度模型,并运用混合整数规划方法,使用Gurobi求解器进行求解。最后,以广东某交通枢纽构造典型算例,对比蓄冰池不同运行方式下的系统运行成本。研究结果表明:有蓄冰池的运行方式降低系统运行成本14.95%,同时提高新能源消纳率3.51%,验证了所提模型和求解方法的有效性。Transportation hubs are important places for energy consumption.The purpose of this paper was to reduce system-operating costs,and reduce carbon emissions.Based on analyzing the natural resource endowment of the transportation hub and the coexistence characteristics of multiple loads such as cooling,heating and electrical,the optimal scheduling model of the integrated energy system of the transportation hub was constructed to reduce the system operating costs.Firstly,an integrated energy system architecture for cold power with new energy power generation and cold storage devices was constructed.The mathematical models of the chiller,ice storage tank and other units in the system were established to provide a basis for the subsequent optimization and scheduling.Secondly,taking the consideration on the constraints of energy supply and energy conversion,the output constraints of energy storage equipment and the constraints of system operation,the optimal scheduling model of the system was constructed,with the goal of increasing the consumption rate of new energy.The mixed integer programming method was employed to solve the problem with the Gurobi solver.Finally,a typical example of a transportation hub in Guangdong was taken to compare the system operation cost and new energy consumption rate of ice storage tank under different operation modes.The results show that the operation mode with ice storage tank can reduce the operating cost by 14.95%and increase the new energy consumption rate by 3.51%,and the effectiveness of the proposed model and solution method is verified.11 tabs,21 figs,24 refs.
