Abstract
In this paper, a new automatic control technique based on fractional-order systems is investi- gated to improve the performance of the Power Systems Stabilizer (PSS), making the Electric Power System (EPS) most efficient. For this, we used the dynamic model of the 10 kVA scaled-down generation system. Initially, two power system stabilizers are tuned and then, a methodology for the design of stabilizers is proposed, based on the fractional-order pole placement (FOPP). The behavior of the lead-lag compensators is performed through simulations, using MATLAB/Simulink. Therefore, we sought to compare the performance of conventional and fractional PSS and, analyzing the results obtained, the system with PSS via fractional pole placement was the one that best dampened the electromechanical oscillations and presented the lowest control effort.
