Supplying grid ancillary services using controllable loads
First Claim
1. A method comprising:
- determining a desired power draw for a plurality of loads connected to an electrical grid, each of the plurality of loads connected to the electrical grid through a load supply control and being able to obtain a total amount of energy to complete a particular task by a specified time; and
transmitting a plurality of instructions through a communication network to a plurality of load supply controls to cause at least some of the loads in the plurality of loads to receive power from the electrical grid at different rates than other loads of the plurality of loads such that the desired power draw is obtained and such that each load of the plurality of loads receives its corresponding total amount of energy to complete the particular task by the specified time.

23. An apparatus comprising:
-
a module configured to communicate with an aggregator through a communications network to register with the aggregator and to receive instructions from the aggregator through the communications network, wherein the instructions are configured to insure that a desired power draw is obtained and that each load of a plurality of loads receives a corresponding total amount of energy to complete a particular task by a specified time; and a mechanism configured to increase or decrease power draw of an associated load in response to the instructions. - View Dependent Claims (24, 25, 26, 27, 28, 31, 32)
