摘要： According to some embodiments, a plurality of heterogeneous data source nodes 130 may each generate a series of current data source node 130 values over time that represent a current operation of an electric power grid. A real-time threat detection computer 150, coupled to the plurality of heterogeneous data source nodes 130, may receive the series of current data source node 130 values and generate a set of current feature vectors. The threat detection computer 150 may then access an abnormal state detection model 155 having at least one decision boundary created offline using at least one of normal and abnormal feature vectors. The abnormal state detection model 155 may be executed, and a threat alert signal may be transmitted if appropriate based on the set of current feature vectors and the at least one decision boundary.
