Abstract: A method for providing grid-forming control of an inverter-based resource includes receiving a negative-sequence voltage feedback of the inverter-based resource. The method also includes receiving at least one negative-sequence feedback signal of the inverter-based resource. The method also includes determining, via a negative-sequence regulator, one or more control signals indicative of a desired negative-sequence impedance of the inverter-based resource using the at least one negative-sequence feedback signal. Further, the method includes generating, via the negative-sequence regulator, a control command for the inverter-based resource based on the one or more control signals. Moreover, the method includes controlling the inverter-based resource based on the control command to achieve the desired negative-sequence impedance of the inverter-based resource.

Abstract: A method for providing grid-forming control of a double-fed generator of a wind turbine includes receiving, via a stator voltage regulator of a converter controller, one or more voltage commands from an external controller. Further, the method includes determining, via the stator voltage regulator, one or more rotor current commands as a function of a magnetizing current command and a stator current feedback signal of the double-fed generator. Thus, the method includes controlling a rotor voltage of the double-fed generator using the one or more rotor current commands to achieve the one or more voltage commands.

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 providing grid-forming control of an inverter-based resource connected to an electrical grid includes providing, via a processor, at least one virtual impedance value of the inverter-based resource. The method also includes determining a voltage drop across the at least one virtual impedance value of the inverter-based resource using at least one current feedback signal, the voltage drop comprising a voltage magnitude and a voltage angle. Further, the method includes receiving one or more voltage or current signals of the inverter-based resource. Moreover, the method includes determining a control command for the inverter-based resource as a function of the voltage drop across the virtual impedance value(s) of the inverter-based resource and the one or more voltage or current signals.

Abstract: The present subject matter is directed to a system and method for regulating reactive power in a wind farm connected to a power grid so as to improve reactive speed-of-response of the wind farm. The method includes receiving a voltage feedback from the power grid and a voltage reference and calculating a linear voltage error as a function of the voltage feedback and the voltage reference. A further step includes generating a first output based on the linear voltage error via a first control path having a first voltage regulator. A further step includes determining a non-linear voltage error based on the linear voltage error via a second control path having a second voltage regulator. A second output is generated via the second control path based on the non-linear voltage error. As such, a reactive power command is generated as a function of the first and second outputs.

Abstract: A method for providing grid-forming control of an inverter-based resource includes receiving, via a controller, a power reference signal. The method also includes determining a dynamic power change limit. Further, the method includes determining, via the controller, an upper power boundary and a lower power boundary for grid-induced power deviations from a desired power operating point based on the power reference signal. Moreover, the method includes determining, via the controller, limits for an inertial power regulator reference based, at least in part, on the upper and lower power boundaries and the dynamic power change limit. In addition, the method includes applying, via the controller, the limits to the inertial power regulator reference in an inertial power regulator of the inverter-based resource.

Abstract: A method for providing grid-forming control of an inverter-based resource includes monitoring the electrical grid for one or more grid events. The method also includes controlling, via a power regulator of a controller, an active power of the inverter-based resource based on whether the one or more grid events is indicative of a severe grid event. In particular, when the one or more grid events are below a severe grid event threshold, thereby indicating the one or more grid events is not a severe grid event, the method includes controlling, via the power regulator, the active power according to a normal operating mode. Further, when the one or more grid events exceed the severe grid event threshold, thereby indicating the one or more grid events is a severe grid event, the method includes controlling, via the power regulator, the active power according to a modified operating mode. Moreover, the modified operating mode includes temporarily re-configuring the power regulator to reduce or eliminate power overloads induced by the severe grid event for as long as the one or more grid events exceed the severe grid event threshold.
