A New Quantum-Class Topper Optimization Based Fractional Order Proportional Integral Power System Stabilizer Design to Damp Out Low Frequency Oscillations in Power Systems

Oscillation with low frequency in grid is a serious issue in power sector. It may effect on performance of the system and even can cause power collapse. To stabilize such oscillation, power system stabilizer (PSS) is used. In this paper, a new quantum class topper based (QCTO) based fractional order proportional integral (FOPI) power system stabilizer (PSS) is proposed to control such oscillations. The parameters of the stabilizer are tuned using QCTO. Integral time square error (ITSE) is chosen as the performance index to design the stabilizer. It is implemented with IEEE type exciter and one machine infinite bus (OMIB). In this paper, two type of exciter such as IEEE type DC1 and IEEE type ST1 excited has been considered for OMIB system. The performance of QCTO based FOPI is compared with QCTO based PI, PID stabilizers. To check the effectiveness of the designed stabilizers, comparative analysis is done with some existing results.
