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 ...

Understanding the Autonomous Electric Vehicle Cyber Threat Landscape: A Focus on Infrastructure, Threats and Ontology‐Based Modelling

Energy Internet, Volume 3, Issue 1, Page 39-51, April 2026.
ABSTRACT The development of autonomous electric vehicles (AEVs) represents the convergence of two simultaneous automotive revolutions: electric vehicles (EVs) and autonomous vehicles (AVs). AVs require sensors, decision‐making systems and actuation systems to achieve autonomous driving, whereas EVs require intelligent management and real‐time ...

Busbar Fault Direction Identification Using Sequences of Displacement Vectors

Engineering Reports, Volume 8, Issue 2, February 2026.
In this paper, a novel busbar fault direction identification scheme is presented. The proposed scheme is based on sequences of displacement vectors. The proposed algorithm is fast and simple enough to be embedded in a differential relay to assist the percentage‐restraint differential algorithm.

Gap‐Loop Active Disturbance Rejection Control: Design and Experimental Validation for High‐Speed Maglev Train Guidance Systems

IET Control Theory &Applications, Volume 20, Issue 1, January/December 2026.
In high‐speed maglev trains, the active guidance system is responsible for centring the vehicle relative to the track, a function that becomes critical under centrifugal forces, crosswinds, and track irregularities. To address the limitations of existing control methods in multi‐disturbance environments, this paper proposes a gap‐loop active ...

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 ...
