There are different types of disturbances in power system such as switching, transient, load variations, which affect stability and efficiency of the power system. These disturbances cause fluctuation at low frequency that are unacceptable, which decreases the power transfer capability in the transmission line and unstable mechanical shaft load. In order to compress low-frequency oscillations, a common solution is to use the Power System Stabilizer (PSS). The Proportional, Derivative, and Integral (PID) controller has the ability to minimize both settling time and the maximum overshoot. In this paper, design of a Proportional, Derivative, and Integral (PID)-based Power System Stabilizer (PSS) and different techniques for tuning of PID-PSS controller are proposed. The parameter of the PID-PSS has been tuned by the Genetic Algorithm (GA), Ant Colony Optimization (ACO), and Firefly Algorithm (FFA) based optimization techniques. Solution results indicate that the performance of Firefly Algorithm (FFA) based PID-PSS controller is much better than the GA and Ant Colony Optimization based PID-PSS controller.
