Advances in Grid-Forming Technology This presentation will report stablished advances in grid-forming (GFM) technology and will discuss about two critical barriers toward the integration of inverter-based resources (IBRs). One barrier is the variability of the primary energy resources such as wind and solar as well as the limitation of battery energy storage to power grid-forming (GFM) IBRs for relatively long periods of time. The other pertains to the ability of GFM IBRs interconnected to infinite capacity grids to regain synchronism after either symmetrical or asymmetrical short circuit faults have been cleared. To address the first barrier, this talk will introduce an advanced GFM IBR powered by geologic hydrogen as well as technical challenges that arise if considering such primary energy resource. To address the second barrier, it is proposed an advanced GFM stabilizer to enhance the stability of IBRs using the classical speed droop law. The latter is inspired from the classical power system stabilizer for synchronous machinery. These advances are critical toward the resilient and reliable integration of IBRs into modern power grids.
