Claim Text:
1. A method of controlling aggregated thermostatically controlled appliances (TCAs) for demand response comprising: a. formulating a targeted load profile; b. generating a forecasted load profile; c. prioritizing the TCAs within a “on” or “off” control group based on their operating temperatures; wherein the prioritizing the TCAs further comprises prioritizing a first “on” group in descending order to turn off the TCA in heating mode, the TCA whose room temperature is closest to the upper thermostat setting is at the top of the queue to be turned off; and a second “off” group in ascending order to turn on the TCA in the heating mode, the TCA whose room temperature is closest to the lower thermostat setting is at the top of the queue to be turned on; d. determining the “on” or “off” status of the TCAs; e. calculating the difference between the forecasted load profile and the targeted load profile to determine the number of TCAs to be turned on or off, wherein the targeted load profile includes combining a baseline load, which is based on the forecasted load profile, with a control signal, the control signal being a load reduction or a load increase signal, and the baseline is a forecast of the TCAs consumptions for the scheduling period; and f. sending command signals to turn on or turn off, in order of priority, the TCAs whose room temperatures are closer to upper or lower thermostat settings of the TCAs.
