Abstract
Description
technical field
[0001] The invention relates to a two-layer planning optimization method of an extended black start scheme for improving the safety of a recovery process, and belongs to the technical field of electric power systems. Background technique
[0002] In recent years, the construction of smart grid has played an important role in improving the reliability of power grid operation, but the possibility of major blackouts still exists in the power grid under the influence of various internal faults and external disturbances. The research on power system recovery control can speed up the process of system recovery after a blackout, reduce the huge economic loss and social impact caused by the blackout, and is one of the important topics of power system security defense.
[0003] According to the tasks and characteristics in different periods of the system recovery process, the system recovery process after a major power outage can usually be divided into three stages: ...
