Method for modeling a repair in an electric grid
View Patent ↗This disclosure describes methods for use with energy management systems that electric utilities use to manage power distribution networks. The methods can account for changes in phase value that dynamic cross-phasing causes in the power distribution network. In one embodiment, the methods facilitate computer-based modeling of the power distribution network to include such changes in phase value into a connectivity model, which provides a schematic representation of the power distribution network.
1. A method of generating a connectivity model of a power distribution network, said method comprising one or more steps for:
inserting, via a processor, a power directing element in the connectivity model, the power directing element having a first node coupled to a first branch of the connectivity model and a second node coupled to a second branch of the connectivity model;
assigning, via the processor, an actual phase value to the power directing element and to the first node and the second node, the actual phase value for the first node and the second node corresponding to, respectively, the first branch and the second branch, wherein assigning the actual phase value is based on information received corresponding to the power directing element and the first node; and
generating, via the processor, the connectivity model with the actual phase values.
2. The method of claim 1 , further comprising updating the actual phase values in response to a change in state of the power distribution network.
3. The method of claim 1 , further comprising changing the location of the power directing element.
4. The method of claim 1 , wherein the first branch comprises a plurality of wires, and wherein the wires carry have different phase values.
5. The method of claim 1 , wherein the power directing element comprises a jumper.
6. The method of claim 1 , wherein the power directing element comprises a switch.
7. The method of claim 1 , further comprising applying a tracing technique to determine the actual phase value for an identified branch in the connectivity model.
8. An energy management system, comprising:
a processor;
memory coupled to the processor; and
one or more executable instruction stored on the memory and configured to be executed by the processor, the executable instructions including one or more instruction for:
generating a connectivity model of an electrical grid on a display, the connectivity model comprising a power directing element having a first node coupled to a first branch of the connectivity model and a second node coupled to a second branch of the connectivity model; and
assigning an actual phase value to the power directing element and to the first node and the second node, the actual phase value for the first node and the second node corresponding to, respectively, the first branch and the second branch, wherein assigning the actual phase value is based on information received corresponding to the power directing element and the first node.
9. The method of claim 6 , further comprising instructions for updating the actual phase values in response to a change in state of the power distribution network.
10. The method of claim 6 , further comprising instructions for changing the location the power directing element.
11. The method of claim 6 , wherein the power directing element comprises a jumper.
12. The method of claim 6 , wherein the power directing element comprises a switch.
13. A computer program product for managing power distribution in an electrical grid, said computer program product including a non-transitory computer readable medium storing one or more executable instructions, the executable instruction causing a computer to implement a method comprising one or more steps for:
inserting a power directing element in the connectivity model, the power directing element having a first node coupled to a first branch of the connectivity model and a second node coupled to a second branch of the connectivity model;
assigning an actual phase value to the power directing element and to the first node and the second node, the actual phase value for the first node and the second node corresponding to, respectively, the first branch and the second branch, wherein assigning the actual phase value is based on information received corresponding to the power directing element and the first node; and
generating the connectivity model with the actual phase values.
14. The computer program product of claim 11 , further comprising updating the actual phase values in response to a change in state of the power distribution network.
15. The computer program product of claim 11 , further comprising changing the location the power directing element.
16. The computer program product of claim 11 , further comprising applying a tracing technique to determine the actual phase value for an identified branch in the connectivity model.
17. The computer program product of claim 11 , wherein the first branch comprises a plurality of wires, and wherein the wires carry have different phase values.
