Abstract: The growing electric vehicle（EV）charging load will produce significant impact on safe operation

of distribution networks. The accommodation capability of EV charging load in traditional AC distribution

networks is limited. AC/DC distribution networks with multi-terminal voltage source converter interconnections

have good power flow control ability and low line loss. Compared with traditional AC distribution networks，it can

effectively improve the accommodation capability of EV charging. Firstly，combining the Markov chain with the

traffic network，the spatial-temporal distribution model of EV charging load under the coupling of road network

was established. Then，considering the power flow control characteristics of VSC in AC/DC distribution network，

an assessment method for accommodating electric vehicle in AC/DC distribution network was proposed，and a twolayer optimizationmodel formaximizing the accommodation capacitywas established. Finally，the influence ofAC/DC network structure and VSC control mode on the accommodation capacity was evaluated through an example.
