A Robust PID Power System Stabilizer Design of Single Machine Infinite Bus System using Firefly Algorithm

This paper presents the design of a proportional-integral-derivative power-system-stabilizer using the firefly algorithm for tuning of stabilizer parameters and washout insert ignore into journalissuearticles values(reset);. The proposed optimization of parameters is carried out with eigenvalue analysis based objective function for two cases to guarantee the stability for the single-machine-infinite-bus system model for a wide range of operating conditions. The system performance with firefly algorithm tuned controller is compared with Bat-Algorithm optimized Conventional-Power-System-Stabilizer controller. The power system robustness is tested on 133 operating conditions. According to the eigenvalue analysis and time response parameters results, the FA-PID-PSS insert ignore into journalissuearticles values(case-II); can stabilize the system for all operating conditions.
