    Abstract: A device to control a genset engine may use multiple feedback loops to provide a fast stable response to load changes. An outer feedback loop may receive frequency measurements and power measurements of a genset engine and determine a dispatch adjustment comprising a frequency setpoint based on the frequency measurements and power measurements. A middle feedback loop may comprise a double deadband droop filter that periodically generates a pulse based on the frequency setpoint and the power measurements. The middle feedback loop may update an inner loop setpoint based on the pulse. An inner feedback loop may alter a target fuel valve reference of the genset engine based on the inner loop setpoint generated by the second controller and a fuel valve droop.

    Abstract: Disclosed is state trajectory prediction in an electric power delivery system. Electric power delivery system information is calculated from measurements by intelligent electronic devices (IEDs), and communicated to a state trajectory prediction system. The state trajectory prediction system may be configured to generate a load prediction profile. The load prediction profile may provide a predicted response of a load at a future time. Further, the state trajectory prediction system may be configured to generate a generator prediction profile that provides a predicted response of a generator at a future time. The state trajectory prediction system may generate a state trajectory prediction based, at least in part, on the load prediction profile and the generator prediction profile. The state trajectory prediction may represent a future state of the electric power delivery system.
