This paper presents a new method to design power system stabilizer (PSS) using fuzzy wavelet neural network (FWNN) for stability enhancement of a multi-machine power system. In the proposed approach, Wavelet Neural Network (WNN) is used to construct a well localized in both time and frequency domains consequent part for each fuzzy rule of a Takagi-Sugeno-Kang (TSK) fuzzy model. In designing the...

This paper is concentrated mainly to the cause and to clear the Power Swings in synchronous generator due to rotor speed oscillations in wind farm which is a distributed generation to maintain the stability of rotor oscillations. The paper presents different conditions of disturbances and faults in specified time period. In Power System Damping Oscillation modes are excited due to disturbance i...

Power system stability enhancement by simultaneous tuning of a Power System Stabilizer (PSS) and a Static Var Compensator (SVC)-based controller is thoroughly investigated in this paper. The coordination among the proposed damping stabilizers and the SVC internal voltage regulators has also been taken into consideration. The design problem is formulated as an optimization problem with a time-do...
