The invention relates to the technical field of power distribution network reconstruction, and more specifically relates to a power distribution network black-start reconstruction method based on minimum expected power outage loss. The power distribution network black-start reconstruction method is evaluated by adopting an economic means, effectively balances the contradictory unity relation between distributed power supply and load recovery, determines the recovery sequence of power-loss nodes and optimizes the recovery path through linear programming and optimization of power distribution network black-start reconstruction, shortens the important load recovery time and reduces the power outage loss.
