摘要
针对电动汽车(EV)大规模接入导致的城市配电网潮流不均衡问题,提出一种计及EV碳排放的交能融合系统出行路径优化及经济运行策略及相应求解方法。首先,梳理城市区域及承担职能,结合Huff模型量化区域出行吸引力,实现对城市精准划分和EV充电负荷数值模拟;其次引入流量加油位置模型(FRLM)评估体系选取适宜充电设备建设点位,规整EV负荷于潮流电网间的映射,进而形成兼顾EV充电服务覆盖度和供电均匀度双向响应的“交通-电力”耦合网络;然后,依据EV出行碳排放量对用户均衡理论做出适应性改进,辅以电网稳定优化导向的潮流均匀度评估函数,建立EV出行路径优化体系,引导局部负荷尖峰合理分摊,保障方案符合经济、低碳运行的预期;最后,依托IEEE 33节点配电网与某城区主干道路网模型进行仿真分析。分析结果,验证了所建模型的有效性与可行性。
To address the unbalanced power flow in distribution networks of urban areas caused by the large-scale grid-connection of electric vehicles(EVs),a method for the optimization of travel routes and economic operation strategies for integrated transportation and energy systems considering EV carbon emissions was proposed,along with corresponding solution methods.The urban areas and their functions were analyzed,and the Huff model was used to quantify the regional travel attractiveness,enabling precise zoning of cities and numerical simulation of EV charging loads.The flow fueling location model(FRLM)evaluation system was introduced to select suitable locations for EV charging stations.This helped organize the mapping of EV loads to the power flow grid,thereby forming a"transportation-energy"coupling network that took both EV charging service coverage and power supply uniformity into consideration.Based on the carbon emissions from EV travel,the user equilibrium theory was adaptively improved,complemented by a power flow uniformity evaluation function guided by grid stability optimization.Then,an EV travel route optimization system that guided the reasonable distribution of local load peaks was established,ensuring that the proposed solution aligned with the expectations for economic and low-carbon operation.Moreover,a simulation analysis was conducted on an IEEE 33 node distribution network and a main road network model of an urban area.The results verified the effectiveness and feasibility of the proposed model.
