Protection of AC and DC Microgrids: Challenges, Solutions and Future Trends [PDF]
, 2015 In future, distributed energy resources (RESs) will be utilized at consumption points. As a consequence, power flow and fault current would be bidirectional and topologydependent; and hence the conventional protection strategies would be inefficient ...

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.

IET Generation, Transmission &Distribution, Volume 19, Issue 1, January/December 2025.This paper proposes a distance protection scheme capable of fault location based on the coordination of control and protection. By utilizing the two fault states provided by IBR control switching, accurate fault location calculation is achieved, unaffected by fault resistance. Additionally, through time‐sequenced coordination of control and protection,

Implementing Enhanced Fault Detection and Classification in DC Microgrids With Savitzky‐Golay Filter
IET Renewable Power Generation, Volume 19, Issue 1, January/December 2025.This paper introduces a methodology for fault detection and classification in DC microgrids. It transforms the measured current from only one end of the protected line into a novel modal current. Then, it employs the second‐order derivative of the Savitzky‐Golay filter to introduce a novel fault detection index for discriminating the faults in a wide ...
