Calculation of Maximum Permissible Load of Underground Power Cables–Numerical Approach for Systems with Stabilized Backfill

Applied Sciences
The maximum permissible load of underground power cables (known in U.S. engineering as “ampacity”) is a function of many parameters, in particular, the thermal resistivity of the native soil.

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 ...

Temperature Estimation Method on Optic–Electric Composite Submarine Power Cable Based on Optical Fiber Distributed Sensing

Photonics
The status of an optic–electric composite high-voltage submarine cable (referred to as submarine cable) can be monitored based on optical fiber-distributed sensing technology, and at the same time, no additional sensor is needed in the monitoring system.

Relaxed Unbalanced Three‐Phase OPF for Operating Envelopes in LV Distribution Grids and Influence of Grid Topology

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This work introduces a relaxed unbalanced three‐phase optimal power flow framework for computing maximum day‐ahead operational envelopes in LV networks. Validation on the IEEE EU LV Testfeeder and 49 real feeders in Brussels demonstrates 7%–10% flexibility gains over fair methods, while a feeder typology analysis highlights the influence of topological
