In-network quick standby coordination and optimization scheduling method used after high-power vacancy accidents

The invention discloses an in-network quick standby coordination and optimization scheduling method used after high-power vacancy accidents. The method includes the steps that firstly, with the maximum of usable power transmitting capacity among all regions and residual standby capacity of all sub regions as the optimization target, meanwhile, the constraint conditions such as province discontinuity surface quota and region standby limit are considered, and an allocation scheme among all provinces and cities of the standby assembling amount is solved; furthermore, an allocation principle among units of the standby assembling amount of all the provinces and cities is obtained. According to the method, through network and province two-level scheduling and coordination control, the coordinated optimization scheduling of province-to-province emergency power support after the high-power vacancy accidents is achieved, and quick processing of power lack disturbance is guaranteed.
