Abstract—This paper presents a decentralized fuzzy controller for a large-scale nonlinear power system and interconnections represented by nonlinear functions. The effectiveness of the proposed decentralized fuzzy controller is illustrated by considering a two-turbo generator system and related load frequency control. The simulation results verify the merits of the proposed controller.

Index Terms—Fuzzy logic control, load frequency control multi-machine power systems.
