SYSTEM AND METHOD FOR OPERATING AN ASYNCHRONOUS INVERTER-BASED RESOURCE AS A VIRTUAL SYNCHRONOUS MACHINE WITH STORAGE

A method for controlling an inverter-based resource having an asynchronous machine connected to a power grid to provide grid-forming control of the inverter-based resource includes coupling at least one additional device to terminals of a first converter of the inverter-based resource. Further, the method includes emulating, via a controller, at least one of the at least one additional device or the first converter as a first virtual synchronous machine. Moreover, the method includes coordinating, via the controller, operation of the first virtual synchronous machine and a second converter of the inverter-based resource using a vector-control approach to control at least one of voltage and frequency at a point of interconnection between the inverter-based resource and the power grid in a closed loop manner.
