In this study, the performance of supplementary stabilizer for static synchronous compensator
(STATCOM) tuned based on genetic algorithms in order to improvement of dynamic stability is studied. Since
STATCOM is usually used for damping Low Frequency Oscillations (LFO), a supplementary stabilizer is
incorporated with STATCOM to reach the mentioned purpose. Genetic Algorithms (GA) as a heuristic
optimization technique is used for tuning the parameters of the STATCOM supplementary stabilizer. The IEEE
14 bus test system is considered for achieving simulation results .In order to show the ability of GA-based
STATCOM to damp LFO, the system responses in case with and without STATCOM are compared. Also two
different operation conditions i.e. normal and heavy have been considered for better examination of GA-based
STATCOM performance. Several nonlinear time-domain simulation tests visibly show the ability of
STATCOM in damping of power system oscillations and consequently stability enhancement.
Key words: Damping of power system oscillations, dynamic stability enhancement, flexible ac transmission systems, genetic algorithms, multi machine electric power system, static synchronous compensator,
