Patent ID: 7778737

Claim:
A method of controlling a local electrical load across a power distribution grid, the method comprising the steps of: a. receiving a one-way communication signal from a remote source having measurement indicia therein, the one-way communication signal being generated when line losses of the power distribution grid exceed a predetermined line loss threshold, the measurement indicia comprising an indication to begin a base-line measurement of line voltage; b. in response receiving to the one-way communication signal, performing a base-line measurement by measuring the line voltage for at least a predetermined time; c. averaging the line voltage across the at least a predetermined time to obtain an average base-line measurement; d. retrieving a differential factor from a local memory, wherein the differential factor is received from the remote source by a communication signal; e. reducing the average base-line measurement by the differential factor to obtain a threshold value; f. monitoring the line voltage; and g. upon the line voltage falling below the threshold value, shedding at least one local electrical load.
