Patent ID: 7778738

Claim:
In a power grid comprising at least one feeder circuit, a method for reducing loss in the feeder circuit comprising: determining both grid structure of at least a part of the feeder circuit and current for the at least a part of the feeder circuit; and based on determining both the grid structure of the at least a part of the feeder circuit and the current in the at least a part of the feeder circuit, selecting at least one customer on the feeder circuit for demand response in order to reduce the loss in the feeder circuit, wherein determining both the grid structure and the current for the at least a part of the feeder circuit comprises using a model that provides an indication of the grid structure for the at least a part of the feeder circuit, wherein the model that provides an indication of the grid structure is based on electrical distance of the at least a part of the feeder circuit from a substation, wherein the model comprises a weighting factor based on the electrical distance of customers from the substation, wherein the model comprises S[1−e −S 0 /S ], wherein S characterizes resistance as a function of distance for the feeder circuit, and wherein S 0 comprises the electrical distance from the substation for customers in the feeder circuit.
