Abstract

This paper presents the design of a proportional-integral-derivative power-system-stabilizerusing the firefly algorithm for tuning of stabilizer parameters and washout (reset). The proposedoptimization of parameters is carried out with eigenvalue analysis based objective function fortwo cases (two parametric bounds) to guarantee the stability for the single-machine-infinite-bussystem model for a wide range of operating conditions. The system performance with FireflyAlgorithmtuned controller is compared with Bat-Algorithm optimized Conventional-PowerSystem-Stabilizercontroller. The power system robustness is tested on 133 operating conditionsto set up the superior performance of FA-PID-PSS over the BA-CPSS. According to theeigenvalue analysis and time response parameters results, it is found that BA-CPSS and FAPID-PSS(case-I) have the ability to stabilize the system for some operating conditions; but theFA-PID-PSS (case-II) can stabilize the system and can improve settling time and overshoot forall operating conditions...
