Providing demand response
First Claim
1. A non-transitory computer-readable medium having instructions stored thereon which, when executed by a processor, cause the processor to:
- receive thermostat data associated with an operating thermostat of a heating, ventilation, and air conditioning (HVAC) system in a structure over a period of time including measured temperatures inside the structure and conditions external to the structure;
determine a first portion of the thermostat data corresponding to steady-state operation periods of the thermostat;
determine a second portion of the thermostat data corresponding to operation periods of the thermostat that are responding to temperature setpoint changes;
determine a third portion of the thermostat data corresponding to operation periods of the thermostat that are transitions between the steady-state operation periods and the operation periods that are responding to temperature setpoint changes; and
create a steady-state model of the thermostat based on the first portion of the thermostat data, a setpoint-change model of the thermostat based on the second portion of the thermostat data, and a transition model of the thermostat based on the third portion of the thermostat data, wherein the setpoint change-model of the thermostat includes;
a rate of temperature change of the structure in response to the HVAC systemactivating or deactivating as a static function of the measured temperatures inside the structure and the conditions external to the structure.

Abstract
Devices, systems, and methods for providing demand response are described herein. One device includes instructions executable to receive thermostat data associated with an operating thermostat of a heating, ventilation, and air conditioning (HVAC) system in a structure over a period of time, determine a first portion of the thermostat data corresponding to steady-state operation periods of the thermostat, determine a second portion of the thermostat data corresponding to operation periods of the thermostat that are responding to temperature setpoint changes, determine a third portion of the thermostat data corresponding to operation periods of the thermostat that are transitions between the steady-state operation periods and the operation periods that are responding to temperature setpoint changes, and create a steady-state model of the thermostat based on the first portion of the thermostat data, a setpoint-change model of the thermostat based on the second portion of the thermostat data, and a transition model of the thermostat based on the third portion of the thermostat data.

8. A computing device for providing demand response, comprising:
-
a processor; and a memory configured to store instructions which, when executed by the processor, cause the processor to; receive thermostat data associated with each of a plurality of sites over a period of time, wherein each respective site includes an operating thermostat of a heating, ventilation, and air conditioning (HVAC) system in a structure; determine an HVAC usage pattern for each of the plurality of sites; receive contextual information associated with each of the plurality of sites; sort the plurality of sites into a plurality of segments based on the HVAC usage pattern and the contextual information; and for each segment; determine a control group of sites; and determine a total baseline energy consumption of sites of the segment active in a demand response event based on an average baseline energy consumption of sites of the control group and a quantity of sites in the segment. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method for providing demand response, comprising:
-
receiving thermostat data associated with an operating thermostat of a heating, ventilation, and air conditioning (HVAC) system in a structure over a period of time; determine a cooling rate associated with the structure based on the thermostat data; determine a self-heating rate associated with the structure based on the thermostat data; and recommend a demand response program type to apply to the HVAC system based on the cooling rate and the self-heating rate, wherein the method includes recommending the duty-cycle program to apply to the HVAC system responsive to a determination that the self-heating rate is above a self-heating threshold and the cooling rate is below a cooling threshold. - View Dependent Claims (16, 17, 18)
