REFINEMENT OF POWER SYSTEM STABILIZER

Dhivya Grace Varghese, Hassena K A

fractional-order power system stabilizer (FoPSS) is introduced to control the frequency and the terminal voltage deviation in a power system connected to an infinite bus. FoPSS yields satisfactory results when there is drastic load change in long transmission lines. MATLAB/Simulink simulation is used to show the improvement of system’s performance when FoPSS is used. FoPSS is more superior to the classical integer-order power system stabilizers (IoPSS)
