In this paper dynamic stability analysis of power system is investigated considering proportional-integral power system stabilizer (P-I PSS) for two-area power system. Gains of P-I PSS are optimized by minimizing an objective function using genetic algorithm (GA). Participation factor method is used to find out the suitable location of PSS. Analysis reveals that the P-I PSS provides sufficient damping for inter-area oscillations and gives better dynamic performances when compared without PSS. Analysis also reveals that the proposed P-I PSS works satisfactorily following a transitory three-phase fault.
