SYSTEM AND METHOD FOR COGNITIVE ALARM MANAGEMENT FOR THE POWER GRID
First Claim
1. A method of cognitive alarm management, said method comprising:
- utilizing at least one processor to execute computer code configured to perform the steps of;
receiving, from a plurality of sensors of a power grid, a plurality of sensor measurements;
transforming the plurality of sensor measurements into a state estimation of the power grid, the state estimation of the power grid including two or more alarms;
determining rankings of the two or more alarms;
simulating power flow resulting from resolution of the two or more alarms in rank-order, according to the rankings of the two or more alarms; and
determining a final ranking of the two or more alarms based on said simulating;
wherein the final ranking of the two or more alarms identifies a causal alarm to be prioritized for resolution.

Abstract
Systems and methods for cognitive alarm management in a power grid are described. In one embodiment, sensor measurements are transformed to determine the state of a power grid. Given current state information relating to the power grid, various analyses of the alarms may be conducted to produce various rankings of the alarms (e.g., by severity, graph analyses, etc.). In an embodiment, using power flow analysis, an optimal ranking is identified from the rankings in which a causal alarm is prioritized for resolution. Given the resolution of the causal alarm, remaining alarms (either all or a sub-set) may be resolved without further action. Thus, an embodiment provides an appropriate ranking of alarm conditions in a power grid such that the optimal resolution of alarms may be achieved. Other variants and embodiments are broadly contemplated herein.
