Energy Science &Engineering, Volume 14, Issue 1, Page 377-398, January 2026.Standard and proposed non‐standard OCR characteristics. ABSTRACT This study introduces an advanced adaptive protection approach for AC power systems, designed to address key limitations in current clustering‐based relay coordination methods. Using K‐means, hierarchical, and spectral clustering techniques, the proposed scheme classifies grid operating ...

IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.This paper proposes the split‐station architecture, which uses high‐temperature superconducting (HTS) cables as ‘virtual bus extensions’ to decouple transformation from distribution in medium‐voltage systems. PYPOWER simulations validated against Project Hydra 13.8 kV specifications demonstrate that a 3‐km HTS link reduces voltage drop by 46 ...

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.This study develops a data‐driven hybrid framework for assessing the condition and risk of converter stations. By combining adaptive thresholding, a condition assessment algorithm and a two‐stage Weibull failure model, it enables early fault detection and quantification of equipment degradation. Case study shows enhanced sensitivity to latent failures,

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 ...
