Abstract

Various aspects of the disclosure provide for an integrated system to facilitate operational and supervisory functions for transmission and distribution power grids. The system can facilitate switching operations for the power grid as well as providing an integrated planning, scheduling, and logging of power grid supervisory functions in order to reduce human error, improve labor efficiencies, and provide tools to assist in daily work plan assignments. The system includes modules to assist with outage and switching management, as well as modules for daily operation planning, work assignment planning, interruption tracking and analysis, and logging and recordkeeping.

3. The system of claim 1, wherein the instructions are associated with managing equipment outage requests, and wherein the managing comprises, receiving requests, submitting the requests, verifying the requests, approving the requests, analyzing the requests, or scheduling the requests.

4. The system of claim 1, wherein the set of tasks comprises issuing a work authorization in response to determining that a safety clearance has been established.

5. The system of claim 1, wherein the operations further comprise:

identifying equipment that is indirectly affected by an outage in response to the switching management operations.

6. The system of claim 1, wherein the facilitating the execution of the switching management operations further comprises extracting data relating to power grid usage and current conditions from a data store and simulating a scenario related to an outage request.

7. The system of claim 1, wherein the maintaining a log record further comprises recording updates and actions associated with the set of tasks.

8. The system of claim 1, wherein the maintaining a log record further comprises recording notifications received from devices associated with the energy management system and a distribution management system.

9. The system of claim 1, wherein the operations further comprise:

determining that a planned outage of the planned outages no longer satisfies the defined criterion associated with an effect on system operation of the power grid system; and

removing a task associated with the planned outage from the set of tasks.

10. The system of claim 1, wherein the determining the action plan is based on information related to a load of the power grid system and a generation capacity of the power grid system.

11. The system of claim 1, wherein the operations further comprise:

determining a contingency action plan based on possible contingencies; and

implementing tasks related to the contingency action plan in response to determining that a contingency of the possible contingencies has occurred.

12. The system of claim 1, wherein the operations further comprise:

collecting an interruption record comprising information associated with cause and effects of an interruption to a normal operation of the power grid system, and wherein the information comprises alarm information collected from a monitoring control and data acquisition alarm system.

13. The system of claim 12, wherein the information also comprises interruption information relating to a number of affected customer identities and a duration of interruption.

14. The system of claim 1, wherein the action plan further comprises a work preparation checklist, a workload assignment, a work list, and details associated with the set of tasks.

15. A method to monitor operation of a power grid system, comprising:
