Abstract

A method for use in monitoring a utility network includes identifying, via a computing device, at least one contingent performance violation associated with a first element of a plurality of transmission elements of a utility network. The method includes presenting by the computing device a risk indicator corresponding to the contingent performance violation around a graphical representation of the first element.

Claims

1. A method for use in monitoring a utility network, said method comprising:

identifying, via a computing device, at least one contingent performance violation associated with a first element of a plurality of transmission elements of a utility network and at least one contingent performance violation associated with a second element of the plurality of transmission elements;

presenting, by the computing device, a graphical representation of the plurality of transmission elements of the utility network as a two-dimensional, one-line diagram; and

presenting, by the computing device, a first risk indicator corresponding to a first contingent performance violation adjacent to and circumscribed around the graphical representation of the first element and a second risk indicator corresponding to a second contingent performance violation adjacent to and circumscribed around the graphical representation of the second element, wherein the second risk indicator is graphically distinguishable from the first risk indicator, and wherein the first and second risk indicators do not change the graphical representation the first and second elements.

2. The method of claim 1, further comprising:

performing, by the computing device, at least one contingency analysis of the utility network; and

storing, by the computing device, contingency analysis results in a memory device.

3. The method of claim 1, wherein identifying the at least one contingent performance violation comprises accessing contingency analysis results stored in a memory device.

4. The method of claim 1, wherein presenting a risk indicator further comprises presenting a risk indicator corresponding to a contingent performance violation that indicates an operational characteristic of the first element is outside a determined range.

5. The method of claim 1, wherein presenting a risk indicator further comprises presenting a risk indicator that indicates one of a severity of the contingent performance violation and a likelihood of the contingent performance violation.

6. The method of claim 1, wherein said presenting the risk indicator corresponding to the contingent performance violation circumscribed around the graphical representation of the first element is performed in response to a user selection input to the computing device.

7. A system for use in monitoring a utility network, said system comprising:

a memory device configured to store a plurality of contingency analysis results associated with a utility network; and

a processor coupled in communication with said memory device, said processor programmed to;

identify at least one contingent performance violation associated with a first element of a plurality of transmission elements of the utility network and at least one contingent performance violation associated with a second element of the plurality of transmission elements;

present, via said display device, a graphical representation of the plurality of transmission elements of the utility network as a two-dimensional, one-line diagram; and

graphically present a first risk indicator corresponding to a first contingent performance violation adjacent to and circumscribed around the graphical representation of the first element and a second risk indicator corresponding to a second contingent performance violation adjacent to and circumscribed around the graphical representation of the second element, wherein the second risk indicator is graphically distinguishable from the first risk indicator, and wherein the first and second risk indicators do not change the graphical representation the first and second elements.

8. The system of claim 7, wherein said processor is further programmed to:

perform at least one contingency analysis of the utility network; and

store the contingency analysis results in said memory device.

9. The system of claim 7, wherein said processor is further programmed to access contingency analysis results stored in said memory device to identify the at least one contingent performance violation.

10. The system of claim 7, wherein said processor is further programmed to graphically present the risk indicator to indicate one of a severity of the contingent performance violation and a likelihood of the contingent performance violation.

11. The system of claim 7, further comprising an input device, wherein said processor is further programmed to present the risk indicator corresponding to the contingent performance violation circumscribed around the graphical representation of the first element in response to a user selection input via said input device.

12. The system of claim 7, further comprising a display device coupled in communication with said processor, wherein said processor is further programmed to present a graphical representation of the risk indicator via said display device.

13. One or more non-transitory computer-readable storage media having computer-executable instructions embodied thereon, wherein when executed by at least one processor, the computer-executable instructions cause the at least one processor to:

identify at least one contingent performance violation associated with a first element of a plurality of transmission elements of a utility network and at least one contingent performance violation associated with a second element of the plurality of transmission elements;

present a graphical representation of the plurality of transmission elements of the utility network as a two-dimensional, one-line diagram; and

present a first risk indicator corresponding to a first contingent performance violation adjacent to and circumscribed around the graphical representation of the first element and a second risk indicator corresponding to a second contingent performance violation adjacent to and circumscribed around the graphical representation of the second element, wherein the second risk indicator is graphically distinguishable from the first risk indicator, and wherein the first and second risk indicators do not change the graphical representation the first and second elements.

14. The one or more non-transitory computer-readable storage media according to claim 13, wherein when executed by at least one processor, the computer-executable instructions cause the at least one processor to:

perform at least one contingency analysis of the utility network; and

store contingency analysis results in a memory device.

15. The one or more non-transitory computer-readable storage media according to claim 13, wherein when executed by at least one processor, the computer-executable instructions cause the at least one processor to identify at least one contingent performance violation at least in part by accessing contingency analysis results stored in a memory device.

16. The one or more non-transitory computer-readable storage media according to claim 13, wherein when executed by at least one processor, the computer-executable instructions cause the at least one processor to present the risk indicator to indicate one of a severity of the contingent performance violation and a likelihood of the contingent performance violation.

17. The one or more non-transitory computer-readable storage media according to claim 13, wherein when executed by at least one processor, the computer-executable instructions cause the at least one processor to present the risk indicator corresponding to the contingent performance violation circumscribed around the graphical representation of the first element in response to a user selection.
