Analysis of Out‐of‐Step Oscillation Centre Migration Under Increasing Renewable Energy Penetration in Large‐Scale Power Systems

IET Smart Energy Systems, Volume 2, Issue 3, Page 181-190, September 2026.
Increasing renewable penetration causes out‐of‐step oscillation centres to migrate away from renewable integration points. Two distinct migration modes—continuous drift and large‐range jumps with instability‐mode changes—are identified, providing guidance for adaptive splitting protection in future power systems.

Field Studies on the Influence of High‐Voltage Direct Transmission Underground Cables on Soils Along the SuedLink Route in Southwest Germany

Journal of Plant Nutrition and Soil Science, Volume 189, Issue 4, Page 479-498, August 2026.
During regular operation of the SuedLink at a load ≤75 %, the average increase in temperature in the plowing horizon is expected to be less than 1.6°C in the soils along the route in Southwest Germany. ABSTRACT Background The SuedLink was planned as a high‐voltage direct‐current underground cable route. The construction itself is a massive intervention
