Abstract: A method for operating a wind turbine power system that supplies real and reactive power to a grid includes operating a generator of the wind turbine power system up to a first speed limit. The method also includes monitoring a wind speed at the wind turbine power system. When the wind speed drops below a predetermined threshold, the method includes reducing the first speed limit of the generator to a reduced speed limit of the generator. Further, the method includes operating the generator at the reduced speed limit for as long as the wind speed remains below the predetermined threshold so as to optimize a tip-speed-ratio of the wind turbine power system during low wind speeds, thereby increasing power production of the wind turbine power system at low wind speeds.

Abstract: A method for estimating grid strength of a power grid connected to a renewable energy farm having a plurality of renewable energy power systems includes measuring, at least, a voltage, an active power, and a reactive power at a point of interconnection of the renewable energy farm to the power grid. The method also includes determining a sensitivity of the voltage to at least one of the active power or the reactive power at the point of interconnection. Further, the method includes determining the grid strength of the power grid as a function of the sensitivity of the voltage to at least one of the active power or the reactive power at the point of interconnection. In addition, the method includes dynamically determining at least one of an active power command or a reactive power command for the renewable energy farm at the point of interconnection based on the grid strength. Moreover, the method includes distributing at least one of the active power command or the reactive power command to individual controllers of the plurality of renewable energy power systems and a farm-level controller of the renewable energy farm.

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.
