IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.This paper maps key 5G technology enablers, such as carrier aggregation, dual connectivity, and network slicing (NS), to IEC 61850 smart grid communication traffic types and experimentally evaluates their performance in commercial 5G networks. Results show that NS enhances reliability for grid protection and automation but still falls short of ultra ...
