چکیده

This paper presents a method for damping of low frequency oscillations (LFO) in a power system. The power
system contains static synchronous series compensators (SSSC) which using a chaotic harmony search
algorithm (CHSA), optimizes the lead-lag damping stabilizer. In fact, the main target of this paper is
optimization of selected gains with the time domain-based objective function, which is solved by chaotic
harmony search algorithm. The performance of the proposed two-machine power system equipped with SSSC is
evaluated under various disturbances and operating conditions and compared to power system stabilizer (PSS).
The effectiveness of the proposed SSSC controller to damp out of oscillations, over a wide range of operating
conditions and variation of system parameters is shown in simulation results and analysis.
