摘要:

为使多能耦合的综合能源系统(IES)在低碳经济运行下可满足负荷多样性的需求,提出一种在电动汽车(EV)不同充电方式下多能耦合的IES低碳经济运行双层优化配置方法.首先,搭建涵盖冷-热-电-气耦合的IES模型.然后,在日内调度运行阶段考虑阶梯碳交易机制以及EV不同充电方式等因素,实现日调度成本最低;在配置规划阶段以设备投资成本与年运行费用总和最低为目标配置设备容量.最后,利用Cplex求解上述两阶段目标函数并通过相互迭代得到最优配置方案与调度结果.结果表明:考虑剩余电量的EV充电方式与碳交易机制能显著降低碳排放量与系统运行成本,所提配置方法可实现多能耦合的IES低碳经济运行.

Abstract:

In order to enable a multi-energy coupling integrated energy system (IES) to meet the needs of load diversity in low-carbon economic operation, a bi-level optimal configuration method for low-carbon economic operation of multi-energy coupling IES in different charging modes of electric vehicles (EVs) is proposed. First, an IES including cold-thermal-electric-gas coupling is established. Then, in the day-to-day operation stage, factors such as hierarchical carbon trading mechanism and different charging modes of EVs are considered to achieve the lowest daily scheduling cost. In the configuration planning stage, based on the daily operation cost, the equipment capacity is configured with the lowest equipment investment cost and annual operation cost. Finally, Cplex is used to solve the above two-stage objective functions and obtain the optimal configuration scheme and scheduling results through mutual iteration. The results show that the charging method considering the remaining charge of EVs and carbon trading mechanism can significantly reduce carbon emissions and operating costs of the system. The proposed configuration approach can well realize low-carbon economic operation of the multi-energy coupling IES.
