Optimal Linear Protection Scheme of Inverter‐Based Distributed Energy Resources: Meeting Fault‐Ride‐Through Requirement

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
This paper presents a new two‐stage protection strategy for active distribution networks that not only addresses selectivity constraints along protected lines but also incorporates fault‐ride‐through (FRT) requirements of inverter‐based distributed energy resources (IBDERs). The proposed coordination strategy (PCS), which distinguishes it from previous
