To reach the climate goals set by national and international institutions, a vast transition of
the legacy power system is unavoidable. The necessary integration of distributed …

Inverter-based resources (IBRs) are playing a major role in modern power systems, and the
installation of IBRs is still growing in recent years, which necessitates the continuous …

The increase of extremely hot days globally has led to more frequent wildfires and frequent
power outages directly and indirectly caused by the wildfires. This has sought an urgency to …

Standards and specifications for inverter-based resources (IBRs) focus primarily on grid-
following (GFL) technologies at present. Therefore, these may generally not be appropriate …

Grid-forming inverters must optimally transfer power from dc-coupled photovoltaic arrays
and batteries into an ac grid. Further, they must be able to restore single-phase induction …

This paper presents a current limitation scheme for a grid-forming inverter-based resource
(IBR). The proposed controller allows the IBR to be integrated into distribution networks …

To facilitate relay operation and mitigate unbalanced voltage conditions, recent
specifications mandate negative sequence control in grid-forming inverter-based resources …

Grid-forming converters in islanded microgrids face power quality problems due to
disturbing loads and possible resonance issues caused by multiple electronically interfaced …

This paper proposes a model to define which inverter-based resources (IBRs) in a given
scenario must have grid-forming (GFM) controllers. The model ensures a minimum grid …

Positive-and negative-sequence equivalent-circuit models are put forth to capture the
operation of grid-forming (GFM) inverters in unbalanced steady-state operating conditions …
