Abstract

Architectures or techniques are presented that can prioritize operating a consumption device in a manner that is efficient in terms of consumption of a resource over satisfying a specified demand assigned to the consumption device. This re-prioritizing can be performed in response to a price of the resource exceeding a threshold.

First claim

What is claimed is:

1. A control device for controlling consumption of a resource, the control device comprising:
a processor; and
a memory that stores executable instructions that, when executed by the processor, cause the control device to at least:
receive real time information that indicates a price of the resource;
determine from the real time information that the price of the resource has exceeded a defined price threshold;
in response to determining the price has exceeded the defined price threshold:
determine a difference in the price and the defined price threshold;
provide the difference in the price and the defined price threshold as input to a function to determine an amount to reduce a first output capacity of a heating, ventilation, and air conditioning (HVAC) device, wherein the first output capacity reduced by the amount is a reduced non-zero output capacity; and
instruct the HVAC device to continue to consume the resource but operate at the reduced non-zero output capacity, without adjustment of an HVAC set point, and without implementation of a setback in which the HVAC device is shut off for a time in order to satisfy the setback.

2. The control device of claim 1 , wherein the control device is caused to instruct the HVAC device to switch from a first mode in which the HVAC device operates at the first output capacity, directly to a second mode in which the HVAC device operates at the reduced non-zero output capacity.

3. The control device of claim 1 , wherein the executable instructions, when executed by the processor, cause the control device to instruct an appliance to switch operation from a first state to a second state in which appliance consumption of the resource or another resource is reduced.

4. The control device of claim 1 , wherein the executable instructions, when executed by the processor, cause the control device to further determine the amount to reduce the first output capacity of the HVAC device based on user input to the control device or the HVAC device.

5. The control device of claim 1 , wherein the executable instructions, when executed by the processor, cause the control device to further at least:
receive further real time information that indicates an updated price of the resource;
determine from the further real time information that the updated price of the resource is less than or equal to the defined price threshold, as the HVAC device operates at the reduced non-zero output capacity; and in response thereto,
instruct the HVAC device to again operate at the first output capacity.

6. The control device of claim 1 , wherein the executable instructions, when executed by the processor, cause the control device to further at least:
determine that the set point is under satisfied by more than an acceptable margin, as the HVAC device operates at the reduced non-zero output capacity; and in response thereto,
instruct the HVAC device to again operate at the first output capacity.

7. A method comprising:
operating a heating, ventilation, and air conditioning (HVAC) device at a first output capacity in order to satisfy a set point, wherein the HVAC device consumes a resource while operating;
receiving real time information that indicates a price of the resource;
determining from the real time information that the price of the resource has exceeded a defined price threshold;
in response to determining the price has exceeded the defined price threshold:
determining a difference in the price and the defined price threshold;
providing the difference in the price and the defined price threshold as input to a function to determine an amount to reduce the first output capacity of the HVAC device, wherein the first output capacity reduced by the amount is a reduced non-zero output capacity; and
operating the HVAC device to continue to consume the resource but at the reduced non-zero output capacity that is less than the first output capacity, without adjustment of the set point, and without implementation of a setback in which the HVAC device is shut off for a time in order to satisfy the setback.

8. The method of claim 7 , wherein the HVAC device is operated to switch from a first mode in which the HVAC device operates at the first output capacity, to a second mode in which the HVAC device operates at the reduced non-zero output capacity.

9. The method of claim 7 , wherein the method further comprises instructing an appliance to switch operation from a first state to a second state in which appliance consumption of the resource or another resource is reduced.

10. The method of claim 7 , wherein the method further comprises determining the amount to reduce the first output capacity of the HVAC device based on user input to a control device or the HVAC device.

11. The method of claim 7 , wherein the method further comprises:
receiving further real time information that indicates an updated price of the resource;
determining from the further real time information that the updated price of the resource is less than or equal to the defined price threshold, as the HVAC device operates at the reduced non-zero output capacity; and in response thereto,
operating the HVAC device again at the first output capacity.

12. The method of claim 7 , wherein the method further comprises:
determining that the set point is under satisfied by more than an acceptable margin, as the HVAC device operates at the reduced non-zero output capacity; and in response thereto,
operating the HVAC device again at the first output capacity.

13. A non-transitory storage medium comprising instructions executable by a processor, wherein the processor implements a method in response to executing the instructions, the method comprising:
operating a heating, ventilation, and air conditioning (HVAC) device to consume a resource, and at a first output capacity in order to satisfy a set point;
receiving real time information that indicates a price of the resource;
determining from the real time information that the price of the resource has exceeded a defined price threshold;
in response to determining the price has exceeded the defined price threshold:
determining a difference in the price and the defined price threshold;
providing the difference in the price and the defined price threshold as input to a function to determine an amount to reduce the first output capacity of the HVAC device, wherein the first output capacity reduced by the amount is a reduced non-zero output capacity; and
operating the HVAC device to continue to consume the resource but at the reduced non-zero output capacity that is less than the first output capacity, without adjustment of the set point, and without implementation of a setback in which the HVAC device is shut off for a time in order to satisfy the setback.

14. The non-transitory storage medium of claim 13 , wherein the HVAC device is operated to switch from a first mode in which the HVAC device operates at the first output capacity, to a second mode in which the HVAC device operates at the reduced non-zero output capacity.

15. The non-transitory storage medium of claim 13 , wherein the wherein the method further comprises instructing an appliance to switch operation from a first state to a second state in which appliance consumption of the resource or another resource is reduced.

16. The non-transitory storage medium of claim 13 , wherein the method further comprises determining the amount to reduce the first output capacity of the HVAC device based on user input to a control device or the HVAC device.
