Supplying grid ancillary services using controllable loads
First Claim
1. A system comprising an aggregator configured to:
- communicate with a plurality of modules through a communications network to register the modules with the aggregator, wherein each of the modules is associated with a corresponding load connected to an electrical grid, each load needing a total amount of energy to complete a particular task by a specific time;
determine a total desired power draw for the plurality of loads;
determine instructions for the modules, wherein the instructions are configured to cause the modules to increase or decrease power draws of the loads in response to the instructions such that that the desired power draw is obtained and that each of the loads receives the corresponding total amount of energy to complete the particular task by the specified time; and
,send the instructions to the modules such that the modules increase or decrease power draws of the loads in accordance with the instructions.

Abstract
A method includes 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 desired amount of energy from the grid in a desired time period, 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 desired amount of energy in the desired time period.

7. A method comprising:
-
determining, by a load supply control associated with a load connected to an electrical grid, a total amount of energy for the load to complete a particular task by a specified time; transmitting, by the load supply control to an aggregator through a communication network, information indicating the specified time and the total amount of energy; receiving, at the load supply control, instructions through the communication network from the aggregator; in response to receiving the instructions, controlling, by the load supply control, the associated load to cause the load to receive power from the electrical grid at a different rate than other loads connected to the electrical grid such that a total desired power draw of the load and other loads is obtained and such that the load receives the total amount of energy to complete the particular task by the specified time. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
