Regional electric-hydrogen generation and charging stationplanning considering electric-hydrogen-road-vehicle collaboration

新能源汽车作为交通领域脱碳发展的关键,其充能需求的补给受基础充能设施布局规划的影响。针对此问题,提出基于电-氢-路-车协同的区域电氢制充注一体站(electric hydrogen generation and charging station,EHGCS)规划方法。首先,建立时间-流量模型分析交通道路的拓扑结构,并采用Dijkstra算法对新能源汽车行驶路径实时模拟,从而建立考虑车-路-网耦合的新能源汽车电氢需求预测模型;其次,分析制取、压缩和存储氢气的全过程,构建EHGCS运行架构和能量流动模型;然后,建立以投资、运行、网损等经济性成本最小为目标的区域EHGCS规划模型,计及路-网耦合约束、配电网和EHGCS设备安全运行约束并利用二阶锥松弛技术求解最优规划方案;最后以某市城区部分干道和IEEE33配电网节点为算例验证所提方法的有效性和实用性。

As the key to decarbonization development in the field of transportation,new energy vehicles have their charging demand replen-ishment affected by the layout planning of basic charging facilities.To address this problem,a regional electric-hydrogen generation and-charging station(EHGCS)planning study based on electric-hydrogen-road-vehicle synergy is proposed.Firstly,a time-flow model is estab-lished to analyze the topology of traffic roads,and Dijkstra is used to simulate the driving paths of new energy vehicles,so as to establish an electric-hydrogen demand prediction model for new energy vehicles considering the vehicle-road-network coupling.secondly,the whole process of producing,compressing and storing hydrogen is analyzed,and the operation architecture and energy flow model of the EHGCS are constructed.Thirdly,the planning model of the regional electric-hydrogen charging station is established with the goal of minimizing the economic costs,such as investment,operation,network loss,etc.,taking into account the constraints of road-network coupling,distribu-tion network and safe operation of equipment,and solving for the optimal planning scheme by using the second-order conical relaxation technique;finally,some arterial roads of urban areas of a certain city and the nodes of the distribution network of IEEE33 are used as the examples to validate the validity and practicability of the proposed methodology.
