Mechanism and Control Analysis of Synchronous Frequency Resonance in Distributed Power Generation System Connected to Grid

Energy Science &Engineering, Volume 14, Issue 4, Page 2263-2276, April 2026.
Small‐signal modeling reveals that insufficient system damping positions conjugate poles near the imaginary axis, fundamentally explaining the SFR mechanism. A virtual resistance control is consequently proposed to damp the resonance and effectively suppress SFR, which is validated through Hardware‐in‐the‐Loop experiments.

Post‐Consumer Mechanical Recycling of Thermally Degraded Glass‐Fiber Reinforced Polyamide 6,6 for Electrical Applications

Macromolecular Materials and Engineering, Volume 311, Issue 4, April 2026.
Post‐consumer mechanical recycling of PA66–GF composite with brominated flame‐retardant is assessed using accelerated thermal ageing to reproduce long‐term thermo‐oxidative degradation typical of electrical devices. Property retention is quantified across virgin, aged, recycled, and diluted recycled states through mechanical testing, microscopy, DSC ...

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 ...
