中文摘要:考虑了热电联产机组(combined heat and power, CHP)以及电动汽车充电站,对具有一定时间跨度的电-气混联综合能源系统规划进行探索。采用基于YALMIP环境下的CPLEX求解器对发电机组、燃气锅炉、CHP机组、输电线路和天然气管道的选址定容问题进行规划,并分场景比较电网与热网耦合及未耦合情况下的运行建设成本,最后将电动汽车充电站纳入规划范围,分别评估几种配置下的系统经济效益。最后,采用6点的综合能源系统模型对提出的方法进行了验证说明。在综合能源系统中采用CHP机组后(场景2)总成本降低17.340百万美元,加入电动汽车负荷后(场景3)总成本降低14.602百万美元。结果表明,电动汽车负荷对降低综合能源系统规划总成本具有显著作用。

Expansion Planning of Integrated Energy System with the Interaction Between Electric Vehicles and Power Grid
Abstract:Taking account of combined heat and power (CHP) and electric vehicle charging stations, this paper explores the electric-gas hybrid integrated energy system planning of a certain time span. The CPLEX solver based on YALMIP environment is used to plan the location and capacity of generators, gas boilers, CHP units, transmission lines and natural gas pipelines, and to compare the construction and operation costs of both coupling and uncoupling of the grid and the heating network. Furthermore, the electric vehicle charging station is included in the planning scope, and the system economic benefits under several configurations are evaluated separately. Finally, the proposed method is validated by a 6-point integrated energy system model. After adopting CHP unit in the integrated energy system (Scenario 2), the total cost is reduced by $17.340mm, and after addition of the electric vehicle load (Scenario 3), the total cost is reduced by $14.602mm. The results show that the electric vehicle load plays a significant role in reducing the total cost of the integrated energy system planning.
