METHOD AND SYSTEM FOR USING DEMAND SIDE RESOURCES TO PROVIDE FREQUENCY REGULATION USING A DYNAMIC ALLOCATION OF ENERGY RESOURCES
First Claim
1. A method comprising:
- grouping loads into a plurality of load aggregations based on electrical power draw characteristics of the loads;
generating a best-fit dispatch signal for each load aggregation to match a desired load response with a sum of predicted load responses of the aggregations each operating in accord with its best-fit dispatch signal; and
for each load aggregation, communicating its best-fit dispatch signal to the loads of the load aggregation.

Abstract
In a direct load control system supporting frequency control of an electrical grid, loads are grouped into a plurality of load aggregations based on electrical power draw characteristics of the loads, e.g. power draw magnitude characteristic and transient slew rate. A best-fit dispatch signal is generated for each load aggregation to match a desired load response with a sum of predicted load responses of the aggregations each operating in accord with its best-fit dispatch signal. For each load aggregation, its best-fit dispatch signal is communicated to the loads of the load aggregation, and the loads of the load aggregation are operated in accord with the best-fit dispatch signal communicated to the loads. The desired load response may be generated based on historical Automatic Generation Control (AGC) signal data and at least one of (1) a weather forecast and (2) daily, weekly, and seasonal cycles.
