Assessment of an Overcurrent Protection Strategy Based on Thermal Stress Curves in Distribution Networks Under Reconfiguration Scenarios

IEEE Access
Network reconfiguration enables the restoration of power supply in interrupted areas after faults or planned maintenance events. However, changes in network topology can often lead to alteration in the direction and magnitude of fault currents ...

The Split‐Station Architecture: Decoupling Transformation From Distribution via Medium‐Voltage Superconducting Virtual Bus Extensions

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 ...

Breakdown Characteristics of PEEK Insulation Immersed in Synthetic Ester Liquid for Subsea Cable Connectors

Electrical Materials and Applications, Volume 3, Issue 1, January/December 2026.
This paper proposes integrating polyether ether ketone (PEEK) with a synthetic ester liquid as the composite insulation system for subsea cable connectors. The study commences with a comparative analysis of the electrical performance of PEEK when immersed in a synthetic ester liquid and a mineral oil.

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.
