storing, at the computer, at least one network hierarchy of the node devices, wherein the at least one network hierarchy of the node devices represents an organizational relationship of the node devices, wherein the at least one network hierarchy of node devices includes a plurality of tiers, wherein at least one tier of the plurality of tiers is based on individual node devices;
detecting an event based on at least one of a current time and an energy demand within the power distribution system;
determining, by the computer, a desired operating limitation of the power distribution system to be optimized to resolve the event;
calculating, by the computer, an effect on the operating limitation based on;
a modification of at least one operating parameter of at least one node device of the plurality of node devices;
at least one of the voltage profile and the power factor profile;
the at least one network hierarchy of the node devices; and
at least one time-based cost function for modifying the at least one operating parameter of the at least one node device; and
transmitting a command, from the computer to the at least one node device, to cause the at least one node device to modify the at least one operating parameter to facilitate optimizing an economic operation of the node devices by balancing efficiency gains with consumer energy costs and revenue changes, wherein the command transmitted from said computer to said at least one node device facilitates optimizing the desired operating limitation to resolve the event.

Abstract
A power distribution system includes a plurality of node devices and a computer communicatively coupled to the node devices. The computer includes a memory area configured to store at least one operating parameter of each of the node devices, and a processor that is programmed to determine a desired operating limitation of the power distribution system to be optimized, calculate an effect on the operating limitation based on a modification of the operating parameter of at least one of the node devices, and transmit a command to the node device to cause the node device to modify the operating parameter.
