Abstract

A method for managing power distribution constraints in a power distribution network can include identifying the constraints at least one of before and during a time the constraint arises, identifying meters that are supplied by a portion of the power distribution network affected by the constraints, confirming an availability of dispatchable devices accessible by the meters, sending messages to the dispatchable devices, monitoring responses generated by the dispatchable devices, determining a resolution of the constraints for a duration of the constraint and resetting each resolution at the end of each constraint.

Claims

1. A method for managing power distribution constraints in a power distribution network, the method comprising:

identifying the constraints at least one of before and during a time the constraint arises;

identifying meters that are supplied by a portion of the power distribution network affected by the constraints;

confirming an availability of dispatchable devices accessible by the meters;

sending messages to the dispatchable devices;

monitoring responses generated by the dispatchable devices;

determining a resolution of the constraints for a duration of the constraint; and

resetting each resolution at the end of each constraint.

2. The method as claimed in claim 1 further comprising in response to a determination that the constraints have been resolved, sending a reset message to the dispatchable devices.

3. The method as claimed in claim 1 wherein the dispatchable devices are devices that can be directly controlled to manage the constraints.

4. The method as claimed in claim 1 wherein the dispatchable devices are at least one of plug-in electrical vehicles and small scale embedded generators (SSEG).

5. The method as claimed in claim 1 wherein the meters are at least one of incorporated in electric vehicle charging stations and associated with small scale embedded generators (SSEG).

6. The method as claimed in claim 1 wherein the messages sent to the dispatchable devices are load dispatch signals that instruct at least one of the dispatchable devices and voltage target signals to appropriate dispatchable devices.

7. The method as claimed in claim 6 wherein the dispatch load signals instruct the dispatchable devices to at least one of reduce a load and increase load generation, and dispatch voltage signals to instruct the dispatchable devices to at least one of reduce a target voltage or increase a target voltage or change target power factor.

8. The method as claimed in claim 1 further comprising monitoring dispatch instructions to the meters to determine a revenue stream.

9. The method as claimed in claim 8 further comprising determining incentives associated with the meters and based on the dispatch instructions to the meters.

10. The method as claimed in claim 9 wherein the incentives can include at least one of billing rates, refunds and constraint payments.

11. A computer program product managing power distribution constraints in a power distribution network, the computer program product including a non-transitory computer readable medium storing instructions for causing a computer to implement a method, the method comprising:

identifying the constraints at least one of before and during a time the constraint arises;

identifying meters that are supplied by a portion of the power distribution network affected by the constraints;

confirming an availability of dispatchable devices accessible by the meters;

sending messages to the dispatchable devices;

monitoring responses generated by the dispatchable devices;

determining a resolution of the constraints for a duration of the constraint; and

resetting each resolution at the end of each constraint.

12. The computer program product as claimed in claim 11 wherein the method further comprises in response to a determination that the constraints have been resolved, sending a reset message to the dispatchable devices.

13. The computer program product as claimed in claim 11 wherein the dispatchable devices are devices that can be directly controlled to manage the constraints.

14. The computer program product as claimed in claim 13 wherein the dispatchable devices are at least one of plug-in electrical vehicles and small scale embedded generators (SSEG).

15. The computer program product as claimed in claim 14 wherein the meters are at least one of incorporated in electric vehicle charging stations and associated with small scale embedded generators (SSEG).

16. The computer program product as claimed in claim 11 wherein the messages sent to the dispatchable devices are load dispatch signals that instruct the dispatchable devices to at least one of reduce a load and increase load generation.

17. The computer program product as claimed in claim 11 wherein the method further comprises:

monitoring dispatch instructions to the meters to determine a revenue stream; and

determining incentives associated with the meters and based on the dispatch instructions to the meters,

wherein the incentives can include at least one of billing rates, refunds and constraint payments.

18. A system for managing power distribution constraints in a power distribution network, the method comprising:

a power distribution system;

a dispatchable load database (DLD) communicatively coupled to the power distribution system; and

a meter data management and communications system (MDMS) communicatively coupled to the power distribution system and the DLD.

19. The system as claimed in claim 18 wherein the power distribution system is at least one of a distribution management system and an outage management system.

20. The system as claimed in claim 18 further comprising a process accessible by at least one of the power distribution system, the DLD and the MDMS, the process configured for:

identifying the constraints at least one of before and during a time the constraint arises;

identifying meters that are supplied by a portion of the power distribution network affected by the constraints, the meters being communicatively coupled to the MDMS;

confirming an availability of dispatchable devices accessible by the meters, the dispatchable devices being registered in the DLD;

sending messages to the dispatchable devices;

monitoring responses generated by the dispatchable devices; and

determining a resolution of the constraints for a duration of the constraint; and

resetting each resolution at the end of each constraint.
