Multi-stage locking verification method for batch load control

The invention relates to the technical field of power system operation and automation control, in particular to a multi-stage locking verification method for batch load control. The method comprises the following steps: A) system locking verification is carried out, and if passing the verification, a step B is carried out; B) region locking verification is carried out on a region in the system, astep C is carried out if passing the verification, or otherwise, the region is locked, and the step is executed on a next region in the system; C) substation locking verification is carried out on a substation, a step D is carried out if passing the verification, or otherwise, the step is executed on a next substation in the region; and D) device locking verification is carried out on a device, the device passes verification if passing the verification, or otherwise, the device is locked, and the step is executed on a next device. The multi-stage locking verification method for batch load control has the substantive e
