Special Issue Information
Dear Colleagues,
The rapid development of high renewable penetration, extensive power electronic interfaces, and complex hybrid grid structures has brought the issues of asymmetry in transmission lines and system operation to the forefront. Asymmetric overhead transmission lines, arising from transposition constraints, tower geometry, or unbalanced loading, present significant challenges for accurate parameter measurement, state estimation, and fault diagnosis. Traditional contact-based measurement methods are often costly, hazardous, and difficult to implement under live-line conditions, driving the need for advanced non-contact measurement technologies that can reliably capture electrical and geometric parameters of asymmetric lines. Furthermore, fault localization in asymmetric renewable power systems is complicated by time-varying topologies, bidirectional power flows, and the presence of both synchronous and converter-interfaced generations, rendering conventional fault analysis methods inadequate. In this context, the interplay between symmetry and asymmetry principles becomes essential—both for understanding the underlying physical characteristics of lines and systems, and for designing robust monitoring and fault detection schemes. Meanwhile, the increasing deployment of real-time sensing, wide-area measurement systems, and digital twin technologies opens new opportunities to capture, model, and mitigate the effects of asymmetry through high-resolution data and advanced analytics.
This Special Issue aims to bring together cutting-edge research on non-contact measurement technologies for asymmetric overhead transmission lines, novel fault location methods tailored for asymmetric new power systems, and the broader impact of symmetry/asymmetry on real-time monitoring and digitalization. We invite researchers to submit original research articles, comprehensive reviews, and applied case studies that address these interconnected topics. Contributions integrating artificial intelligence, machine learning, and data-driven techniques for asymmetry characterization, measurement data processing, and intelligent fault diagnosis are particularly encouraged.
