UAV‐Assisted Fault Location Coordinated Strategy for Resilient Distribution Systems
IET Generation, Transmission &Distribution, Volume 19, Issue 1, January/December 2025.Disasters may also damage the communication infrastructure, resulting in untimely reporting of fault information detected by remote fault indicators (RFIs). In this paper, we propose a UAV‐assisted coordination strategy for status collection and fault location in distribution systems.
