摘要：
In order to guide the ordered charging of electric vehicles（EVs），a pricing strategy of EV fast charging price considering space-time equilibrium and elastic response of load is proposed. The traffic flow theory is introduced to describe the traffic network and the space-time distribution model of EV fast charging load is established. Considering the elastic demand of distribution network scheduling and EV fast charging load，the pricing framework of fast charging price under the source-load interaction is constructed. Based on the power flow tracking method，the calculation method of fast charging price is derived from the space-time dual dimension. On this basis，considering the elastic response characteristics of EV load and aiming to improve the load balance of distribution network，a pricing strategy of fast charging price is established，which is solved by an iterative algorithm. The simulative results show that the proposed pricing strategy can effectively guide the ordered fast charging of EVs，motivate the friendly interaction between EV users and distribution network，and improve the space-time distribution balance of load. © 2024 Electric Power Automation Equipment Press.
