Abstract

There are different types of disturbance in power system like switching, transient, load variation, etc., which affects stability and efficiency of power system. These disturbances cause fluctuation at low frequency which are unacceptable, as they decrease the power transfer capability in transmission line and unstable mechanical shaft load. In order to compress low frequency oscillation, a common solution is the use of Power System Stabilizer (PSS). This paper provides Ant Colony Optimization (ACO) algorithm based approach for robust and optimal design of power system stabilizer proposed for the single machine infinite bus hydro governor turbine generator. The proposed design of the controller is formulated as a parameter optimization problem based eigenvalues, damping ratio, and time domain analysis. The simulation results by proposed design approaches when compared with conventional PSS show better results.
