The recent development of protection coordination schemes based on inverse of AC microgrid: A review

IET Generation, Transmission &Distribution, Volume 18, Issue 1, Page 1-23, January 2024.
The traditional OCR faced many protection performance challenges and miss‐coordination events due to the high DG penetration. Therefore, the main goal of using the voltage value that the relay discovers is to offer reliable relay coordination under high DG penetration.

A New Current Fingerprinting Sensing Method for Adaptive Protection of PV-Integrated Distribution Networks

Sensors
Grid-following photovoltaic (PV) inverters inject fault currents whose magnitude and phase are set by the control mode active during the disturbance, so directional overcurrent relay (DOCR) settings coordinated for one inverter response can miscoordinate
