Abstract—The centralized control of large scale systems is usually infeasible due to their high dimensionality, nonlinearity, coupling, time delay and etc. In order to overcome the mentioned difficulties, this paper presents an application of decentralized fuzzy logic controller (FLC) which is optimum by Simulated Annealing (SA) algorithm on two interconnected power area for the load frequency control as a case study of large scale systems. The simulation study is undertaken, based on MATLAB / SIMULINK to demonstrate and confirm the effectiveness of proposed method.

Index Terms—Fuzzy logic control; simulated annealing optimization method, large scale systems; load frequency control.
