- As a result of the increasing amount of energy transmission over a long distance, low frequency Inter-area oscillations have been becoming an increasingly important concern in the planning and operation of practical power systems. This undesirable phenomenon may cause very serious results, such as the loss of interconnects, load curtailments and even system blackouts. Abundant of power system stabilizers have been developed by the researchers in the past few years, but the area is still open for the efficient power stabilizer development which can efficiently able to handle the power oscillations without increasing the system controller system complexity. This paper presents a novel way to achieve fast and efficient damping of Inter-area oscillations and improve the dynamic stability of interconnected power systems by designing of an Sugeno type Fuzzy-PID hybrid controller for efficient Inter-area power oscillation damping in two area four machine power system. The most important point for using Sugeno type fuzzy inference over mamdani fuzzy inference is that it is much more suitable for linear PID like controllers. The implementation of the proposed work is with the Simulink of MATLAB 2012(b).This paper also present a complete comparative analysis of Inter-area power oscillation damping capabilities of proposed Sugeno type Fuzzy-PID hybrid controller based power system stabilizer (Hybrid-PSS) and conventional PID controller based power system stabilizer (PID-PSS) and with no controller (No-PSS) at line to ground (LG) fault condition. The obtained results shows that the Inter-area power oscillation damping capability of proposed Sugeno type Fuzzy-PID hybrid controller based power system stabilizer (Hybrid-PSS) is much higher than the conventional PID-controller based PSS. In addition to this the damping time required by proposed Sugeno type Fuzzy-PID hybrid controller.
