Comprehensive Analysis of Transmission-level Fault Impacts on 3-phase and 1-phase Distribution Inverter-based Resource Operation

Transmission-level faults can trigger significant tripping of distributed 3-phase and 1-phase inverter-based resources, leading to power imbalances and voltage quality issues. Tailored fault-ride-through mechanisms for 1-phase inverter-based resources may be necessary to mitigate these effects.
