Abstract

A method, a system, and computer readable medium for managing thermostatically controlled loads (TLCs). The method includes acquiring data from a plurality of TCLs including at least thermal parameters associated with each TCL of the plurality of TCLs and a regulation signal data and prioritizing the plurality of TCLs. The prioritization is based on a contribution of each TCL to an overall service. The method further includes generating an optimization curve based on the prioritization, determining an optimization attribute associated with each TCL of the plurality of TCLs, and outputting the optimization attribute associated with each TCL for a regulation period to each TCL. The optimization curve has at least reward criteria as an optimization parameter.

Claims (55)

1. A method for managing thermostatically controlled loads (TCLs), the method comprising:

acquiring, using communication circuitry of a central controller, data from a plurality of TCLs including at least thermal parameters associated with each TCL of the plurality of TCLs and a regulation signal data;

prioritizing, using processing circuitry of the central controller, the plurality of TCLs based on a contribution of each TCL to an overall service;

generating, using the processing circuitry, an optimization curve based on the prioritization, the optimization curve having at least a reward criteria as an optimization attribute;

determining, using the processing circuitry, the optimization attribute associated with each TCL of the plurality of TCLs; and

outputting, using the communication circuitry, the optimization attribute associated with each TCL for a regulation period to each TCL,

wherein the prioritizing step includes

identifying a number of TCLs in a homogeneous control group,

determining a service provision capability index (SPCI) for each TCL, the SPCI being a function of a service quality and wear-and-tear of each TCL, and

ranking the TCLs based on the determined SPCIs.

2. The method of claim 1 , further comprising:

identifying a subset of the plurality of TCLs based on the prioritizing; and

sending command signals to the subset of the plurality of TCLs during a subsequent regulation period.

3. The method of claim 1 , wherein the acquiring further includes:

acquiring operation data from a set of TCLs; and

including a TCL in the plurality of TCLs when the operation data indicates that the TCL is participating in the regulation period.

4. The method of claim 1 , wherein the wear-and-tear of each TCL is a function of a ratio of switching index and the service quality is determined based on a power mismatch.

5. The method of claim 1 , wherein determining the optimization attribute further includes:

generating a maximum service capacity curve; and

wherein the optimization attribute is a function of the optimization curve and a total reward attribute.

6. The method of claim 1 , wherein the prioritizing further includes determining a maximum service capacity for each TCL based on a bisection method.

7. The method of claim 1 , wherein the TCL is a heat pump, an air conditioning system, a ventilation system, a water heater, a freezer, or a refrigerator.

8. The method of claim 1 , wherein the regulation period ranges from one hour to twenty-four hours.

9. A system for managing thermostatically controlled loads (TCLs), the system comprising:

a plurality of TCLs; and

a central controller configured to:

acquire data from the plurality of TCLs including at least thermal parameters associated with each TCL of the plurality of TCLs and a regulation signal data,

prioritize the plurality of TCLs based on a contribution of each TCL to an overall service,

generate an optimization curve based on the prioritization, the optimization curve having at least a reward criteria as an optimization attribute,

determine the optimization attribute associated with each TCL of the plurality of TCLs, and

output the optimization attribute associated with each TCL for a regulation period to each TCL, wherein the prioritizing includes

identify a number of TCLs in a homogeneous control group,

determine a service provision capability index (SPCI) for each TCL, the SPCI being a function of a service quality and wear-and-tear of each TCL, and

rank the TCLs based on the determined SPCIs.

10. The system of claim 9 , wherein the central controller is further configured to:

identify a subset of the plurality of TCLs based on the prioritizing; and

send command signals to the subset of the plurality of TCLs during a subsequent regulation period.

11. The system of claim 9 , wherein the acquiring further includes:

acquire operation data from a set of TCLs; and

include a TCL in the plurality of TCLs when the operation data indicates that the TCL is participating in the regulation period.

12. The system of claim 9 , wherein the wear-and-tear of each TCL is a function of a ratio of switching index and the service quality is determined based on a power mismatch.

13. The system of claim 9 , wherein the central controller is further configured to:

generate a maximum service capacity curve; and

wherein the reward attribute is a function of the optimization curve and a total reward attribute.

14. The system of claim 9 , wherein the TCL is a heat pump, an air conditioning system, a ventilation system, a water heater, a freezer, or a refrigerator.

15. The system of claim 9 , wherein the regulation period ranges from one hour to twenty-four hours.

16. A non-transitory computer readable medium storing computer-readable instructions therein which when executed by a computer cause the computer to perform a method for managing thermostatically controlled loads (TCLs), the method comprising:

acquiring data from a plurality of TCLs including at least thermal parameters associated with each TCL of the plurality of TCLs and a regulation signal data;

prioritizing the plurality of TCLs based on a contribution of each TCL to an overall service;

generating an optimization curve based on the prioritization, the optimization curve having at least reward criteria as an optimization attribute;

determining an optimization attribute associated with each TCL of the plurality of TCLs; and

outputting the optimization attribute associated with each TCL for a regulation period to each TCL, wherein the prioritizing step includes

identifying a number of TCLs in a homogeneous control group,

determining a service provision capability index (SPCI) for each TCL, the SPCI being a function of a service quality and wear-and-tear of each TCL, and

ranking the TCLs based on the determined SPCIs.
