A WIDE RANGE ROBUST PSS DESIGN BASED ON POWER SYSTEM POLE-PLACEMENT USING LINEAR MATRIX INEQUALITY

Mohammad Ataei – Rahmat-Allah Hooshmand – Moein Parastegari

   In this paper, a new method for robust PSS design based on the power system pole placement is presented. In this stabilizer, a feedback gain matrix is used as a controller. The controller design is proposed by formulating the problem of robust stability in a Linear Matrix Inequality (LMI) form. Then, the feedback gain matrix is designed based on the desired region of the closed loop system poles. This stabilizer shifts the poles of the power system in different operational points into the desired regions in s-plane, such that the response of the power system will have proper damping ratio in all the operational points. The uncertainties of the power system parameters are also considered in this robust technique. Finally, in order to show the advantages of the proposed method in comparison with conventional PSS, some simulation results are provided for a power system case study in different operational points.

Keywords: power system stabilizer (PSS), robust stability, linear matrix inequality (LMI) problem, pole
