IET Energy Systems Integration, Volume 7, Issue 1, January/December 2025.ABSTRACT Frequency stability is vital to power system operation, especially in interconnected power systems (IPS) and smart grids where renewable energy sources and load fluctuations introduce unpredictability. This variability and time delay from decentralised control configurations can impair load frequency control (LFC) and compromise system ...
