A method for operating an asynchronous inverter-based resource connected as a virtual synchronous machine to a power grid to provide grid formation control thereof includes receiving a frequency reference command and / or a voltage reference command. The method further includes determining at least one power reference signal for inverter-based resources based on the frequency reference command and / or the voltage reference command. Further, the method includes generating at least one current vector using the power reference signal (s). Further, the method includes determining one or more voltage control commands for the inverter-based resource using the at least one current vector. Further, the method includes controlling the inverter-based resource based on the one or more voltage control commands such that the inverter-based resource actively participates in controlling at least one of a voltage and a frequency at the point of interconnection between the inverter-based resource and the power grid in a closed loop manner.
Description
technical field [0001] The present disclosure relates generally to inverter-based resources, such as wind turbine power systems, and more particularly to operating grid-connected inverter-based resources with asynchronous machines as virtual synchronous machines to provide inverter-based A system and method for grid formation control of resources. Background technique [0002] Wind power is considered to be one of the cleanest and most environmentally friendly energy sources currently available, and wind turbines have received increasing attention in this regard. Modern wind turbines typically include a tower, generator, gearbox, nacelle and one or more rotor blades. Rotor blades capture the kinetic energy of the wind using the known airfoil principle. For example, rotor blades typically have an airfoil cross-sectional profile such that during operation, air flows over the blades, creating a pressure differential between the sides. Thus, a lift force directed from the pre...
