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.
