  • Patent number: 11329487
    Abstract: A system and method are provided for controlling a power generating system having at least one power generating subsystem connected to a point of interconnection (POI). Accordingly, the subsystem controller of the power generating subsystem obtains a first data signal indicative of an electrical parameter at the POI and a second data signal indicative of the electrical parameter at the generating subsystem. The second data signal has a higher fidelity than the first data signal. The second data signal is utilized by the subsystem controller to generate a first modeled value for the electrical parameter at the POI which compensates for the lower-fidelity first data signal. The subsystem controller generates a setpoint command for the power generating subsystem based, at least in part, on the first modeled value for the electrical parameter.

  • Patent number: 11319920
    Abstract: A hydrodynamic power generation assembly and method of use therefor for generating electrical power from the combination of kinetic energy, hydrostatic energy, and turbulent energy of water. The power generation assembly comprises a water accelerator assembly comprising a support structure which is at least partially buoyant and a baffle panel member (or an array of baffle panel members) having an opening, inter-panel spacing, or flow passageway around the baffle panel(s). A hydropower converter is supported from, by, or on the support structure and is operatively coupled to a generator. The hydropower converter is positioned behind baffle assembly. Water flowing through or around the baffle assembly has an increased velocity relative the ambient current and therefore is capable of generating more power relative to the ambient water where power generation assembly is deployed. Particular types of hydropower converters suitable for use with the invention are turbines and water wheels.
