Abstract

This paper presents a new load frequency control (LFC) scheme for multi area power system. The power systems under study is uncertain due to unknown parameters. The indirect adaptive fuzzy control technique is used to design tracking controller by generating approximations of unknown functions. Suitable adaptive control law and updating algorithms for the controller parameters are synthesized using Lyapunov function. The designed tracking controller for each area uses the frequency and tie-line power deviations of the area. The proposed controller guarantees the boundedness of the closed-loop signals. Simulation results of a three-area power system are presented to validate the effectiveness of the proposed.
