Abstract: A method for damping power oscillation in a power system includes generating synchronized generator speed signals by time stamping a plurality of generator speed signals. The synchronized speed signals are transmitted to a control station for determining power oscillations in the power system. The control station provides damping control signals to a plurality of damping devices based on power oscillations in the power system.

Abstract: A control method for increasing reactive power generation of a wind turbine having a Doubly-Fed Induction Generator (DFIG) includes obtaining, by a control device having one or more processors and one or more memory devices, wind forecast data of the wind turbine. Further, the method includes generating, by the control device, a real-time thermal model of the DFIG of the wind turbine using the wind forecast data. More specifically, the thermal model defines a thermal capacity for the DFIG that does not exceed system limits. Thus, the method also includes dynamically adjusting, by the control device, a reactive power set point of the DFIG of the wind turbine based on the real-time thermal model.

Abstract: A method for optimizing reactive power generation of an electrical power system includes generating, via a plurality of cluster-level controllers, a cluster-level reactive power command for each cluster of electrical power subsystems based on a system-level reactive power command. The method also includes determining, via the cluster-level controllers, a subsystem-level reactive power command for each of the electrical power subsystems based on the cluster-level reactive power command. Further, the method includes evaluating, via a plurality of subsystem-level controllers, reactive power capability of a plurality of reactive power sources within each of the electrical power subsystems. Moreover, the method includes generating, via each of the subsystem-level controllers, an actual reactive power for each of the electrical power subsystems based on the evaluation by allocating a portion of the subsystem-level reactive power command to each of the plurality of reactive power sources.

Abstract: The present disclosure is directed to a system and method for optimizing operation of a wind turbine. The method includes providing a voltage regulator between a power grid and the wind turbine. The voltage regulator is configured to control at least one voltage condition of the wind turbine. Another step includes monitoring, via one or more sensors, at least one operating condition and at least one voltage condition of the wind turbine. The method also includes comparing, via a controller, at least one of the operating condition or the voltage condition with a predetermined threshold to determine a margin-to-threshold ratio. Thus, a further step includes controlling the voltage regulator based on the comparison so as to maximize the margin-to-threshold ratio.
