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 hybrid HVDC converter system includes a DC bus, at least one capacitor commutated converter (CCC) and at least one self-commutated converter (SCC) coupled in series through the DC bus. The CCC induces a first voltage on the DC buses, the SCC induces a second voltage on the DC bus, the first voltage and the second voltage are summed to define a total DC voltage. The method includes at least one of regulating the total DC voltage induced on the DC buses including regulating the first DC voltage through the CCC and regulating the second DC voltage through the SCC substantially simultaneously, regulating the total DC voltage induced on the DC bus including regulating the second DC voltage through the SCC, and regulating the total DC voltage induced on the DC bus including regulating the first DC voltage through the CCC.

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.

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.

Abstract: A method for operating a inverter-based resource connected to a power grid includes receiving one or more voltage feedback signals created by at least one component of the inverter-based resource, wherein distortion components of the one or more voltage feedback signals are more sensitive to voltage distortion created by the inverter-based resource than by external sources of voltage distortion. Further, the method includes extracting a distortion component of the one or more feedback signals having a certain phase sequence and frequency. Moreover, the method includes determining a voltage command for the power converter as a function of, at least, the distortion component. Thus, the method includes controlling the power converter based on the voltage command such that the voltage distortion created by the at least one component of the inverter-based resource is reduced in a manner that is relatively insensitive to voltage distortion created by sources external to the inverter-based resource.
