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

Multiphysics Simulation Analysis of Submarine Cable Topology Considering Environmental Constraints

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
The article establishes a high‐accuracy electromagnetic‐thermal coupled multiphysics model for predicting the ampacity of submarine cables, with results showing minimal error compared to the IEC standard. It also analyses the loss distribution across cable layers under different conditions and explores the impact of environmental factors like wind ...

Advanced Hosting Capacity Assessment in Distribution Systems Using a Centralised HIL‐Based Setup

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
The paper proposes a two‐stage framework for assessing distributed energy resource (DER) hosting capacity that combines an initial optimisation‐based estimate with real‐time validation using a centralised IEC 61850–compliant Hardware‐in‐the‐Loop (HIL) platform and a digital twin of the IEEE 33‐bus system.

The effect of PV modules on temperature conditions of nearby power cables

Frontiers in Energy Research
The highest permissible load of power cables (ampacity) depends strongly on the ambient temperature, which in the case of cables surrounded by free air is generally assumed to be 25°C.

Surge impedance loading aware reactive power management system for offshore oil and gas facilities

Results in Engineering
Long HVAC submarine cables inject substantial charging MVARs. They cause the Ferranti effect at the receiving end and also shrink the cable’s ampacity margin. This paper presents a Surge Impedance Loading Aware Reactive Power Management System (SILARPMS)
