Abstract A three-phase unbalanced random fuzzy dynamic power flow method for active distribution network(ADN) containing energy hubs(EHs) with priority utilization of wind power is proposed, Firstly, the daily wind power was described by random fuzzy variables. The cooling/heating and electric improved coupling mode of EH's priority utilization of wind power and its exchange power model with ADN were proposed through the comparison of the daily cooling/heating and electric loads. Then, the three-phase unbalanced random fuzzy dynamic power flow model of ADN with EHs that use wind power preferentially was established by considering the wind power penetration level of direct access distribution network and exchange power of EH, the interaction states of source, load and islands between ADN and transmission network. Finally, the model was solved by combining random fuzzy simulation, back/forward sweep method and unbalanced three-phase decoupling. From the simulation results of the improved IEEE 33-bus system, it is suggested that the proposed method can effectively improve the wind power utilization rate of EH, and the daily scheduling power flow results with random fuzziness and volatility are more comprehensive and objective.

Key words： Active distribution network wind power energy hub random fuzzy dynamic power flow three-phase unbalanced
