Abstract

A method for regenerating switching plans based on changing power distribution network conditions includes updating a power distribution network model in response to a power distribution network event, identifying areas of the power distribution network affected by the power distribution network event, identifying switching plans that are impacted by the power distribution network event and regenerating the switching plans that are impacted by the power distribution network event.

Claims

1. A method of regenerating switching plans based on a change in a power distribution network associated with the switching plans, the method comprising:

updating a power distribution network model in response to a power distribution network event, the power distribution network event representing a change in at least one area of the power distribution network;

identifying the at least one area of the power distribution network affected by the power distribution network event;

identifying switching plans that are impacted by the power distribution network event, each of the switching plans corresponding with a fault isolation and recovery solution for the at least one area of the power distribution network; and

regenerating the switching plans that are impacted by the power distribution network event.

2. The method as claimed in claim 1 further comprising receiving a plurality of power distribution network events.

3. The method as claimed in claim 2 further comprising filtering the plurality of power distribution network events for one or more events that may affect switching plans.

4. The method as claimed in claim 1 further comprising analyzing the switching plans that are impacted by the power distribution network event.

5. The method as claimed in claim 4 further comprising recalculating the switching plans that are impacted by the power distribution network event.

6. The method as claimed in claim 4 wherein recalculating the switching plans that are impacted by the power distribution network event include at least one of re-running restoration algorithms on the areas affected by the power distribution network event, and incrementally calculating the switching plans that are impacted by the power distribution network event.

7. The method as claimed in claim 5 further comprising identifying intersections between the switching plans that are impacted by the power distribution network event and the power distribution network model.

8. The method as claimed in claim 1 further comprising executing at least one of switching plans that are not impacted by the power distribution network event and regenerated switching plans that are impacted by the network event.

9. A non-transitory computer readable medium storing instructions which, when processed by a computer cause the computer to implement a method of regenerating switching plans based on a change in a power distribution network associated with the switching plans, the method comprising:

updating a power distribution network model in response to a power distribution network event, the power distribution network event representing a change in at least one area of the power distribution network;

identifying the at least one area of the power distribution network affected by the power distribution network event;

identifying switching plans that are impacted by the power distribution network event, each of the switching plans corresponding with a fault isolation and recover solution for the at least one area of the power distribution network; and

regenerating the switching plans that are impacted by the power distribution network event.

10. The computer readable medium as claimed in claim 9 wherein the method further comprises receiving a plurality of power distribution network events.

11. The computer readable medium as claimed in claim 10 wherein the method further comprises filtering the plurality of power distribution network events for one or more events that may affect switching plans.

12. The computer readable medium as claimed in claim 9 wherein the method further comprises analyzing the switching plans that are impacted by the power distribution network event.

13. The computer readable medium as claimed in claim 12 wherein the method further comprises recalculating the switching plans that are impacted by the power distribution network event.

14. The computer readable medium as claimed in claim 12 wherein recalculating the switching plans that are impacted by the power distribution network event include at least one of re-running restoration algorithms on the areas affected by the power distribution network event, and incrementally calculating the switching plans that are impacted by the power distribution network event.

15. The computer readable medium as claimed in claim 13 wherein the method further comprises identifying intersections between the switching plans that are impacted by the power distribution network event and the power distribution network model.

16. The computer readable medium as claimed in claim 9 wherein the method further comprises executing at least one of switching plans that are not impacted by the power distribution network event and regenerated switching plans that are impacted by the network event.

17. A system to regenerate switching plans based on changing power distribution network conditions in a power distribution network, the system comprising:

a fault detection, fault isolation and recovery (FDIR) system communicatively coupled to the power distribution network, the FDIR system configured to perform regeneration of the switching plans;

a network model manager communicatively coupled to the FDIR system; and

an event filter communicatively coupled between the power distribution network and the network model manager, and configured to filter power distribution network events that impact the switching plans for the power distribution network, the power distribution network events representing a change in at least one area of the power distribution network.

18. The system as claimed in claim 17 wherein the FDIR system is configured to re-evaluate the switching plans impacted by the power distribution network events.

19. The system as claimed in claim 18 wherein the FDIR system is further configured to perform the regeneration based on recalculating the switching plans that are impacted by the power distribution network events, wherein recalculating the switching plans that are impacted by the power distribution network events include at least one of re-running restoration algorithms on the areas affected by the power distribution network events and incrementally calculating the switching plans that are impacted by the power distribution network events.

20. The system as claimed in claim 18 wherein the FDIR system is further configured to identify intersections between the switching plans that are impacted by the power distribution network events and a power distribution network model.
