Data‐Driven Hybrid Approach for Condition and Risk Assessment of Secondary Equipment in Converter Stations

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,

Adaptive Protection Coordination for Microgrids Using Dual‐Setting Directional Overcurrent Relays: A Real‐Time HIL Validation Approach

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 ...

Multi‐point‐line Grounding Fault Section Identification in Urban Distribution Networks by Using Coordinated Multi‐Source Data

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.
