Claim:
1. A method for controlling an electrical distribution system, the electrical distribution system comprising a first segment supplied by a first substation and a second segment supplied by a second substation, the method comprising: when a fault occurs at the second substation and the second substation is disconnected from the second segment by opening a second switch device, connecting the first segment and the second segment by closing a first switch device there between thereby supplying power from the first segment to the second segment, simultaneously performing: by a second controller associated with the second substation, an active power loss reduction optimization of the second segment and by a first controller associated with the first substation, a voltage violation check on the first segment to determine a voltage deviation of the first segment; sending an indicator by the second controller to the first controller regarding a status of the active power loss reduction optimization of the second segment, providing, by the second controller to the first controller, data representing a minimum voltage associated with the second segment while completing the active power loss reduction optimization of the second segment; and performing, by the first controller, upon receiving from the second controller the indicator, wherein the status indicates completion of the active power loss reduction optimization on the second segment by the second controller, an active power loss reduction optimization on the first segment.
