Hierarchical Coordinated Optimization Method for Urban Transportation Network-Fast Charging Station-Distribution Network
摘要
Abstract
With the continuous advancement of transportation electrification,the coupling degree between the urban transportation network(UTN)and the distribution network(DN)is gradually increasing,which makes the calculation of traffic flow and power flow more complex.In order to comprehensively describe the impact of electric vehicles on UTN and DN,this paper proposes a dispatching strategy of hierarchical coordinated optimization for UTN-fast charging station(FCS)-DN based on dynamic traffic flow and power flow to realize the economical and flexible operation of UTN,FCS and DN.First,the power flow optimization is carried out in the DN optimization layer with the goal of minimizing the operation cost,the traffic flow assignment is carried out based on the mixed user balance in the UTN optimization layer,and the electric vehicles are dispatched with the goal of maximizing the operator's revenue in the FCS optimization layer.Then,in order to simplify the model,the traffic flow allocation problem is transformed into the constraints of the FCS revenue model and linearized,and then the alternating direction method of multipliers is used to solve the above problem to protect the information privacy of various subjects.Finally,the effectiveness of the proposed model is verified by the system coupled with the IEEE 33-bus distribution network and the Nguyen-Dupuis transportation network.关键词
