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

Abstract: A system for strategic operation of a variable generation power plant includes a computing device in communication with a data store including environmental data independent system operator rules, operator risk metrics, power storage systems, a maintenance schedule, and a capacity record. The computing device including a statistical modeling unit to generate a risk-to-revenue strategic bid estimate for successive time periods based on one or more factors accessible in the data store, a display device to display a graphical representation of the risk-to-revenue strategic bid estimate; and a control processor that analyzes the risk-to-revenue strategic bid estimate to schedule the daily operation of a power storage system and to identify one or more time periods of the successive time periods in which to perform a scheduled maintenance. A method and a non-transitory computer readable medium are also disclosed.
