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.
