Overhead Line Ampacity Forecasting With a Focus on Safety

IEEE Transactions on Power Delivery, 2022
Predictions of the ampacity of overhead lines can be framed in a general context that aims to make electric grids highly efficient and reliable. In this paper, a methodology is presented that provides ampacity forecasts, which are valid for both the very short term, such as a few minutes or hours, and longer terms, up to 24 hours ahead.

A Novel Bipolar DC Connection Strategy for Photovoltaic Power Plants With a 50% Reduction in DC Cabling Length

Energy Science &Engineering, Volume 14, Issue 9, Page 4230-4247, September 2026.
Bipolar configuration is a new topology in the direct current (DC) system of photovoltaic power plants, which is topologically analogous to the bipolar configuration utilised in High‐Voltage Direct Current power transmission systems. DC cable length and copper usage are reduced by 50% using a bipolar configuration.

Overload capacity analysis of extra high voltage AC XLPE submarine cable

Frontiers in Energy Research, 2023
When submarine cable line fails or other lines need load transfer, it often suffers from emergency ampacity that exceeds the steady-state ampacity. The layout environment of the submarine cable is always complex and changeable, and the overload capacity ...

Evaluating Extraction of Magnesium and Lithium Compounds from Seawater Using Byproducts of Demonstration‐Scale Bipolar Membrane Electrodialysis

ChemSusChem, Volume 19, Issue 16, 27 August 2026.
Integrating multiple seawater‐based processes could improve efficiency and reduce process costs. Here, we assess combining mineral extraction with a demonstration‐scale bipolar membrane electrodialysis (BPMED) unit. Acid and base streams from BPMED are used for lithium and magnesium recovery from seawater, presenting a sustainable method for marine ...
