Design of SVC controller for oscillations damping using Self-learning fuzzy approach

Application of fuzzy PD controller based on self learning algorithm for SVC device has been investigated in this paper. This approach used sensitivity model for learning Self Learning Fuzzy Logic parameters. This has been improved by adding up an integral term whose gain coefficient is also synthesized by learning that is actuated after completion of the main learning algorithm. The paper considers the conventional PID controller and compares its performance with respect to the proposed SLFLC controller. Several fault and load disturbance simulation results are presented to emphasize the efficiency of the proposed SVC controller in a TNB 25bus of south Malaysian power system and New England 39 Bus system.
