1. A method for controlling an operation of devices in a power distribution network, said network including at least two power sources, a plurality of feeders and a plurality of switching devices positioned along the feeders and being in communications with each other, said network being represented by a plurality of teams where each team includes one side of adjacent switching devices and loads and power line sections therebetween, where a plurality of teams define divisions in the network and one of the switching devices in each division is assigned as being a leader device, said method comprising:
determining that there is a power loss in the network and one or more of the teams is not receiving power;
performing a switching process in one of the switching devices to prevent current from flowing to the power loss;
initiating a power restoration process to control the open and closed status of the switching devices to isolate the power loss;
performing the power restoration process by the leader device in the division that the power loss is occurring that includes opening and closing switching devices so that power is provided to all of the teams except the team that the power loss is in;
reconfiguring the divisions based on which switching devices are now open; and
selecting new leader devices based on the reconfiguration of the divisions.
