[Objective] After multiple line failures， a distribution network can maintain load supply by forming multiple microgrids. The initial formation and subsequent dynamic interconnection of microgrids require consideration of frequency-voltage control and sequential coordinated output of various types of resources. Hence， this paper proposes a multi-source sequential coordinated power-supply recovery method for post-disaster distribution networks， incorporating droop-control-based dynamic networked microgrid technology and network reconfiguration methods. [Methods] First， a pre-disaster electric vehicle dispatch model is established， considering the impact of impending extreme events on user travel intentions. Subsequently， a sequential power-supply recovery model is established that comprehensively considers the output of distributed resources， reverse charging of electric vehicles， repair crew dispatch， and flexible load management with the integration of frequency-voltage control constraints. Finally， multiple sets of examples are designed to validate the proposed method. [Results] The dynamic networked microgrid technology incorporating droop control can reduce the load-shedding ratio during faults to 30% of that without considering dynamic interconnections. [Conclusions] This effectively lowers the amount of load shedding while ensuring the safety of load restoration， providing an important reference for power-supply recovery of distribution networks under extreme events.
