AGGREGATE LOAD MANAGEMENT AT A SYSTEM LEVEL
First Claim
1. A method for aggregate load management, comprising:
- determining whether a load capacity limit within a utility power network will be exceeded;
selecting an aggregated demand reduction target to remain within capacity bounds if the load capacity limit is to be exceeded;
selecting a demand reduction strategy; and
sending a control signal that includes a randomized pulse width modulation level, based on the strategy selected, to a controller in at least one load component of the utility system based on the aggregated demand reduction target.

Abstract
A method for aggregate load management includes determining whether a load capacity limit within a utility power network will be exceeded, selecting an aggregated demand reduction target to remain within capacity bounds if the load capacity limit is to be exceeded, selecting a demand reduction strategy, and sending a control signal that includes a randomized PWM level, based on the strategy, to a controller in a load component of the utility system based on the reduction target. A method for component load management includes receiving a control signal from a utility system based on a utility demand reduction strategy, converting the signal into randomized PWM control of the load component in accordance therewith, receiving an updated control signal based on utility system monitoring of an aggregate load of a component of the utility system, and converting the updated signal into randomized PWM control of the load component in accordance therewith.

20. A method for load management at a component level, comprising:
-
receiving, via a controller in a load component, a control signal from a utility system based on a utility demand reduction strategy; converting the control signal into a randomized pulse width modulation control of the load component in accordance with the control signal; receiving, via the controller in the load component, an updated control signal from the utility system based on utility system monitoring of an aggregate load of at least one component of the utility system; and converting the updated control signal into a randomized pulse width modulation control of the load component in accordance with the updated control signal.
