Abstract: In this paper decentralized load frequency control (LFC) for suppression of oscillations in multi-area power systems using fuzzy logic controller was studied. A three area system is considered in which areas 1 and 2 and areas 1 and 3 are connected by HVDC transmission links and areas 2 and 3 are connected by normal AC tie-line. The performance of the fuzzy logic controller is compared with the conventional PI controller and the simulation results shows that fuzzy logic controller is very effective enhancing better damping performance in non-linear conditions.
