Investigation of Sub-Cycle Overvoltages Experienced by Inverter-Based Resource (IBR) Plants Due to System Disturbances

IEEE Access
IEEE Std 2800-2022 marks a major step forward in defining minimum technical requirements for connecting inverter-based resources (IBRs) to the Bulk Power System (BPS). However, as the standard gains wider adoption and real-world implementation progresses,
