This paper
presents the design of a proportional-integral-derivative power-system-stabilizer
using the firefly algorithm for tuning of stabilizer parameters and washout
(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 (case-II) can stabilize the system for all operating conditions.
