摘　　要：电动汽车(electric vehicle,EV)的大规模发展,使得交通网转变为电动汽车和燃油车(gasoline vehicle,GV)随机混合出行的复杂网络;配电网也转变为供需双侧不确定、“源-网-站-储”高效互动的低碳型电网。在新型交通-配电网耦合系统下,亟需研究交通和配电网的联合规划方法,以满足EV时空充电需求,保障交通和配电网的安全可靠运行。为此,基于EV和GV的实时能耗特性差异,建立了混合交通流分配模型,以充分反映GV对EV出行和充电行为的影响,进而建立了混合交通流下的交通网多阶段规划模型。此外,考虑储能型柔性开关(energy storage integrated soft open points,E-SOP)的运行特性,协同“源-网-站-储”,建立了E-SOP影响的配电网多阶段规划模型。结合交通-配电网物理和“流量-功率”耦合约束,实现了交通-配电网的联合规划。根据Sioux Falls交通网和IEEE 69节点配电网组成的耦合系统算例测试,验证了所提联合规划模型比独立规划的总成本减少了7.21%,并且E-SOP的接入能减少系统无功出力和电压波动。The large-scale development of electric vehicles(EVs)has transformed the transportation network into a complex network with random and mixed travel of EVs and gasoline vehicles(GVs),and the distribution network has also been a low-carbon grid with uncertain supply and demand,including the interaction of source-grid-station-storage.In the transportation-distribution coupling system(TDCS),it is urgent to develop a coordinated planning method to meet the spatiotemporal charging needs of EVs and ensure the safe operation of the TDCS.Therefore,based on the real-time energy consumption characteristics of EVs and GVs,a mixed traffic flow assignment model is established to better reflect the influence of GVs on the travel and charging behavior of EVs.Then,a multistage planning model of the transportation network in mixed traffic flow is established.Considering the operational characteristics of energy storage integrated soft open points(E-SOP),and cooperating with source-grid-station-storage,a multistage planning model of the distribution network affected by E-SOP is established.Combining with the physical and flow-power coupling constraints,a coordinated planning model is proposed.Based on the case studies of the Sioux Falls transportation network and IEEE 69-node distribution network coupling system,it is verified that the coordinated planning method can reduce the total planning cost by 7.21%compared to separate planning,and E-SOP can reduce the reactive power output and voltage fluctuation of the system.
