  • System and methods for controlling a power generating asset having a non-deliverable component of a total power output
    Patent number: 11870386
    Abstract: The system and method described herein provide control for a power generating asset having a double-fed generator connected to an electrical grid. Accordingly, a non-deliverable component and a deliverable component of a total power output of a generator of the power generating asset is determined via a controller. A compensation module of the controller then determines a first control signal based, at least in part, on the non-deliverable component. The first control signal is configured to establish a modified rotor current setpoint. Additionally, a buffer module of the controller then determines a buffer control signal for a DC energy buffer based, at least in part, on the non-deliverable component. The DC energy buffer is operably coupled between a line-side converter and a rotor-side converter of a power converter of the power generating asset.
