Toughness improving method of power distribution network and terminal

According to the power distribution network toughness improvement method and the terminal provided by the invention, uncertainty of power distribution network fault recovery time is considered in a fault recovery process, a power distribution network multi-stage fault recovery model is established by taking minimum weighted insufficient power supply as a target, and maintenance personnel scheduling and mobile emergency power supply vehicle scheduling are taken as optimization variables; and carrying out coordinated scheduling on the maintenance personnel and the mobile emergency power supply vehicle according to a model solving result. Compared with the prior art that the fault recovery time is considered as a known condition and the coupling influence process among post-disaster maintenance personnel scheduling, mobile emergency power supply vehicle scheduling and the fault recovery time is ignored, the method comprehensively considers the uncertainty of the fault recovery time and the multi-stage process of
