Online prognosis for priority power supply restoration
Automatic monitoring of the vulnerability of the power supply to a high-priority facility has important practical considerations. As opposed to the well studied optimization task for power supply restoration which is carried out after a fault has happened, the task of analyzing the restorability of a high-priority line under possible fault conditions is a decision problem that has to be solved periodically as the load conditions in the network change. The outcome of this decision problem may be used to alert the high-priority facility about the vulnerability of the state of the network, in the sense that some faults may cause a non-restorable outage to the line supplying that facility. This paper studies the prognosis of a high-priority line in a network in terms of power supply restorability and proposes the first method for this problem.
