IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.This research presents a robust protection coordination strategy using dual‐setting directional overcurrent relays (DS‐DOCRs) and a novel optimisation approach to address challenges in adaptive protection. A modified objective function, incorporating primary and backup relay operating times along with coordination time intervals (CTIs), is designed to ...

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.A multi‐source data collaborative fault section identification method for high fault‐tolerant distribution networks is proposed. The method constructs a robust mixed‐integer linear programming cooperative model by integrating zero‐sequence current direction features and fault indicator alarm signals.

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.This paper proposes a closed‐form analytical framework predicting the sub‐cycle transient peak currents of grid‐following and grid‐forming inverters during short‐circuit faults. The method uniquely decouples the fault current into a hardware natural response and a control‐commanded response, enabling rapid estimation of instantaneous initial peaks ...

Instantaneous Frequency-Based Algorithm for Directional Relays
, 2021 The looped structure of the transmission and subtransmission networks results in the bidirectional fault current passing through the protection relays. The detection of the current direction is relegated to the directional protection unit.

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 ...
