This paper presents the enhancement of dynamic stability of Multi Machine with the help of FACT devices. If there is lack of damping torque in power system then it can lead to fluctuations and instability. For the solution to this problem, power system stabilizers (PSSs) have been widely used to improve power system stability. Where due to few drawbacks of the conventional PSSs, the need for finding a better substitution still remains. In this paper, the application of a Flexible AC

Based upon the modal analysis and singular value analysis, the dynamic voltage stability analysis is carried out. The proposed approach has the advantages of the classical static voltage stability analysis and the modern multi-variable feedback control theory. The values and vectors are calculated for frequencies corresponding to the critical system modes. This proposed method is also applicable to very large systems.
