Self-learning fuzzy SVC controller for oscillations damping

this paper investigates the use of self learning fuzzy PD controller applied to SVC device for improving damping inter-area modes of oscillations. The SLFLC utilizes sensitivity model for learning of SLFLC parameters. This has been enhanced by adding 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 KeywordsSVC devices; Power system oscillations; Fuzzy logic controllers (FLC); self learning fuzzy logic controller (SLFLC); Damping oscillation.
