Variance‐Empirical Mode Decomposition Method for Fault Detection in MMC‐HVDC Transmission Lines
Energy Science &Engineering, Volume 14, Issue 10, Page 4626-4640, October 2026.A variance‐embedded empirical mode decomposition (VEMD) method is proposed for fast and accurate fault detection in MMC‐HVDC transmission lines. By combining variance analysis with EMD, the method reliably detects various faults without communication links and remains robust to noise and non‐fault transients.

Design and Deployment of a Regulation‐Compliant Infrared Heating System for UK Field Trials
Plant-Environment Interactions, Volume 7, Issue 5, October 2026.ABSTRACT Free‐air warming systems are essential for simulating climate change in field conditions, yet most are not designed to meet UK or EU health and safety standards. We present the design and field deployment of a hexagonal temperature‐free air controlled enhancement (T‐FACE) system that meets UK and EU health and safety requirements for outdoor ...

A Novel Digital Twin Platform for Accelerating Power Systems Restoration
Energy Internet, Volume 3, Issue 2, Page 111-141, July 2026.Hardware Architecture Design of DT System in Laboratory. ABSTRACT With the global energy structure transforming towards the goal of net zero emissions, the penetration of an inverter‐based resource (IBR) in power systems is increasing. This transformation poses two critical challenges: the system post blackout restoration process becomes extremely ...

Engineering Reports, Volume 8, Issue 6, June 2026.Power system protection devices are vulnerable to adversarial samples. We propose a digital twin and reinforcement learning framework. It trains a virtual model within safe operational boundaries, reducing the false operation rate to below 3.5%. The model's inference delay is under 10 ms, meeting real‐time protection requirements.
