In introduction, this paper investigates the application of TCSC hybrid controller for improving damping inter-area modes of oscillations. The proposed controller comprised fuzzy logic proportional and derivative controller with the conventional proportional and integral controller (FUZZY PD + PI) turn by genetic algorithm techniques. Approaching the proposed control scheme implements the characteristics of the GA’s global optimization to optimize the FPID control parameters, KP, KI and K to obtain the best control effect by minimizing the integral time square error online. The performance of the proposed hybrid control in increasing the damping of local and inter-area modes of oscillation is demonstrated in a two area four machine 11-bus systems and a practical reduce system of south Malaysian power network called TNB 25-bus system. Results shows that this type of hybrid control is proved to be more robust and effective in damping electromechanical oscillations of the power systems in comparison with the conventional PID regulators used for TCSC control. The GA optimization technique is also found to be effective and efficient in tuning the FPID parameters.
