Power System Stabilizers (PSS) are appropriate for nominal conditions of networks and can induce the required damping; but, with changes in the working condition, systems will encounter some difficulties. Power System Stabilizers 3 Band (PSS3B) as another type of stabilizers shows better results with changes in the working conditions of systems. On the other hand, after determining the remarkable result of Flexible AC Transmission System (FACTS) equipment in oscillation damping, nowadays, this equipment is increasingly used in power systems. Regarding the nonlinearity of power systems, it is not appropriate to use linear methods for calculating their parameters. In this paper, Hybrid Big Bang-Big Crunch (HBBBC) algorithm was applied for consistently designing PSS3B parameters in four generators of a two-area 11 and control parameters of static VAR compensator considered in this network. Then, to investigate the effect of changing system conditions on stability, working conditions of generators were changed in two steps and a comparison was made between PSS and PSS3b and the calculated parameters in the initial mode.
