An Enhanced Slime Mould Algorithm Optimized LFC Scheme for Interconnected Power Systems

Abstract

Load frequency control (LFC) is a crucial motif of power system stability since it regulates the divergences of system frequency and tie-line power. This paper proposes a new optimized fractional-order (FO) LFC for a multi-area interconnected power system based on the slime mould algorithm (SMA). The developed controller combines two FO controllers including the tilt-derivative controller with filter (TDF) and a hybrid fractional-order controller. Additionally, future electric vehicles (EVs) installations are expected to participate in the LFC. The superiority and the effectiveness of the SMA tuned controller are confirmed by performing different comparative analyses with featured controllers in the literature under various step load disturbances and significant disruption of renewable energy sources (RESs). The results of the simulation demonstrate the proposed controller's ability to improve system response.
