In this study, effects of Thyristor Controller Series Compensator (TCSC) Static Synchronous Series Compensator (SSSC) and United Power Flow Controller (UPFC) on power systems are investigated. In 65 buses system, effects of the points where voltage stability is Maximum Loading Parameter (MLP) and the Minimization Line Losses (MLL) are investigated by FACTS devices. Relations between voltage and maximum load parameters and power losses between the lines are illustrated by figure. According to the acquired results; UPFC are more efficient than SSSC and TCSC in terms of both voltage stability and line losses.
