Abstract: An electrical power system includes a system-level controller and a plurality of clusters of subsystems defining a stator power path and a converter power path for providing power to the power grid. The converter power path includes a partial power transformer. The system further includes a cluster transformer connecting each cluster to the power grid and a plurality of cluster-level controllers communicatively coupled with the system-level controller. Each of the clusters is communicatively coupled with one of the cluster-level controllers. Thus, the system-level controller regulates system-level active and/or reactive power based on required active or reactive power for the system, respectively, and compares the system-level active or reactive power with preferred values thereof. Further, the system-level controller receives feedback signal(s) from the cluster-level controllers, generates cluster-level power command(s) based on the comparison and the feedback signal(s), and sends the cluster-level power commands to the cluster-level controllers.

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.
