DETERMINING THE SEVERITY OF A GEOMAGNETIC DISTURBANCE ON AN ELECTRICAL NETWORK USING MEASURES OF SIMILARITY

摘要

Methods, systems, and computer program products for determining the severity of a geomagnetic disturbance on an electrical grid through similarity measures are provided herein. A method includes extracting multiple features of activity associated with geomagnetically induced currents from multiple heterogeneous data streams; comparing the extracted characteristics with historical data relating to the geomagnetically induced currents to determine a level of similarity between each of the extracted features and the historical data; assigning a severity level to one or more of the extracted features having a level of similarity to the historical data above a given threshold; and generating a notification comprising (i) a prediction of the activity associated with the geomagnetically induced currents based on the extracted characteristics having a level of similarity with the historical data above a given threshold, and (ii) the severity level attributed to him.
