A Novel Hybrid Event‐Based System Separation and Response‐Driven Under‐Frequency Load Shedding Scheme in a Standalone Power System With Renewables

IET Generation, Transmission &Distribution, Volume 19, Issue 1, January/December 2025.
This work proposes a new hybrid event‐based and response‐driven special protection scheme (SPS) designed for standalone power systems with renewables: the event‐based strategy employs tied breakers to separate the power system, preventing the renewable resource from tripping before the under‐frequency load shedding (UFLS) (e.g., 81L) relays is ...
