MULTI-MODAL, MULTI-DISCIPLINARY FEATURE DISCOVERY TO DETECT CYBER THREATS IN ELECTRIC POWER GRID

摘要

According to some embodiments, a plurality of heterogeneous data source nodes may each generate a series of data source node values over time associated with operation of an electric power grid control system. An offline abnormal state detection model creation computer may receive the series of data source node values and perform a feature extraction process to generate an initial set of feature vectors. The model creation computer may then perform feature selection with a multi-model, multi-disciplinary framework to generate a selected feature vector subset. According to some embodiments, feature dimensionality reduction may also be performed to generate the selected feature subset. At least one decision boundary may be automatically calculated and output for an abnormal state detection model based on the selected feature vector subset.
