Abstract: The example embodiments are directed to a system and method for forecasting load flexibility of a power grid. In one example, the method includes receiving temperature values associated with temperature set points of a plurality of loads that are included on a power grid, forecasting a flexibility of the plurality of loads using a polynomial-time mixed-integer non-linear programming (MINLP) optimization based on the received temperature values for the plurality of loads, and outputting information about the forecasted flexibility for display to a display device. The MINLP optimization performs the forecasting of the load flexibility on a fine-grained basis in comparison to conventional methods and is still fast enough that it can be computed in real-time.

Abstract: Systems and methods for improved anomaly detection for rotating machines. An example method may include determining that power generation is to be performed based on a voltage instead of a power factor; receiving a command voltage; receiving a measured voltage value from a first location in a power generation network; determining that the measured voltage value from the first location is less than the command voltage value; determining that a current value associated with a transmission line at the third location is less than a threshold current value; determining that a reactive power of a power generation component at a third location is less than a maximum reactive power of the component; and increasing, based on the determination that the reactive power of the component at the third location is less than a maximum reactive power of the component, the reactive power of the component.

Abstract: An electric power system includes a generating unit, which includes a controller for controlling an operational mode of the generating unit. The electric power system also includes an event estimator communicatively coupled to the controller of the generating unit and a network estimator communicatively coupled to the event estimator. The network estimator includes a processor configured to receive status information associated with the electric power system, determine, based upon the status information, at least one characteristic of the electric power system, and transmit the at least one characteristic to the event estimator.
