Synchronous Condensers and Grid-Forming Control for the Integration of Inverter-Based Resources in Weak Grids
Power systems with a higher share of inverter-based resources (IBR) exhibit reduced system strength and inertia, which are otherwise provided by synchronous generators (SG). This is because IBRs do not have the rotational inertia of SGs, and they do not contribute to short-circuit fault currents as …
