he purpose of this paper is to control with new tactic of FACTs device to expand the first swing stability of
power system. Generally, the speed based control technique (e.g. Bang -bang control) is used but this scheme is not able
to use complete decelerating area to maintain stability. In SMIB system normally proposed control strategy is applied to
SVC. It is found that this policy can provide expressively huger stability limit then that of the bang-bang control method.
