    Abstract: A method for providing grid-forming control of an inverter-based resource includes receiving, via a controller, one or more reference commands from an external controller. The method also includes determining, via the controller, one or more control commands for the inverter-based resource based on the one or more reference commands. Further, the method includes determining, via the controller, at least one feedforward signal as a function of the one or more control commands, one or more control signals, and one or more estimated electrical conditions of the inverter-based resource. The method also includes using the feedforward signal(s) to position at least one control angle of the inverter-based resource to an anticipated value needed to achieve the one or more reference commands, thereby enabling rapid response to the one or more reference commands received from the external controller.

    Abstract: A method for controlling a dual-fed induction generator (DFIG) connected to a power grid in response to a high-voltage grid event includes receiving, via a controller, a frequency signal of the power grid. The method also includes filtering the frequency signal via a filtering assembly so as to determine whether certain types of grid conditions are present in the power grid. The filtering assembly includes a first filter connected in parallel with a second filter. The first filter has a bandwidth that is greater than the second filter. Further, the method also includes comparing output signals of the first and second filters of the filtering assembly to one or more frequency thresholds. Moreover, the method includes controlling the DFIG based on the comparison.

    Abstract: The present subject matter is directed to a system and method for operating an electrical power circuit connected to a power grid. The power circuit includes a power converter electrically coupled to a generator. The method includes monitoring at least one speed condition of the generator during operation of the power circuit. Another step includes determining one or more voltage conditions of the power circuit. The method also includes calculating a maximum reactive current for the generator as a function of at least one of the speed condition or the one or more voltage conditions. Thus, the method also includes operating the generator based on the maximum reactive current so as to prevent an actual modulation index of the power converter from exceeding a predetermined threshold.

    Abstract: A method for maintaining sufficient reactive current margin in a power system connected to a power grid includes receiving, via a power limiter system, a reactive current command and an upper reactive current limit for the power system. The method also includes determining, via the power limiter system, a reactive current margin signal as a function of the reactive current command and the upper reactive current limit. Further, the method includes generating, via the power limiter system, a power command signal based on the reactive current margin signal. Moreover, the method includes controlling, via a system controller, operation of the power system based at least partially on the power command signal.

    Abstract: In one aspect, a method for controlling the operation of a power generation system configured to supply power to an electrical grid may generally include monitoring a rotor speed of a generator of the power generation system and determining a gain scaling factor based on the rotor speed, wherein the gain scaling factor increases with decreases in the rotor speed across a range of rotor speeds. In addition, the method may include adjusting a regulator gain to be applied within a current regulator of the power generation system based on the gain scaling factor and applying the adjusted regulator gain within the current regulator in order to generate a voltage command signal for controlling a power converter of the power generation system.

    Abstract: The present disclosure is directed to a system and method for stabilizing sub-synchronous interaction (SSI) of a wind turbine generator connected to a power grid. More specifically, the method includes measuring an alternating-current (a-c) quantity of the power grid. Another step includes converting the a-c quantity to a d-q quantity and providing the d-q quantity to a d-q control loop within the controller. Another step includes altering, with a symmetric control component, a transfer function of the d-q control loop. The method also includes generating at least one d-q reference signal for the wind turbine generator based on the altered transfer function so as to achieve symmetric control of the generator. A further step includes generating a control signal for the generator based, at least in part, on the at least one d-q reference signal. The method also includes operating the generator based on the control signal.

    Abstract: The present disclosure is directed to a system and method for improving reactive current response time in a renewable energy power system connected to a power grid. The method includes providing, via a controller of the power system, a permissive logic relating to the power grid. Another step includes determining, via a controller of the renewable energy power system, a reactive current reference command for the renewable energy power system in response to the permissive logic being satisfied. The method also includes generating, via the controller, a reactive current pulse command for the renewable energy power system. Thus, the controller is configured to determine a total reactive current command by combining the reactive current reference command and the reactive current pulse command. Further, the method includes operating the renewable energy power system based on the total reactive current command so as to improve the current response time.
