Abstract: This article Firefly Algorithm is used as evolutionary technique for the best assignment of flexible AC transmission systems (FACTS) is a unified system. Reactive Power load taken base to 125% base loading and the system presence with FACTS devices. The lines and buses recognized to connect the FACTS devices using New Voltage Stability Index (NVSI).FACTS devices along with reactive generation of generators using Firefly algorithm. The test and Validation is performed on IEEE 30 bus and 72 bus Real time systems. Effectiveness of placement of FACTS devices is established by comparing the results reported in literature.
Keywords:  FACTS devices, Firefly Algorithm, Differential Evolution Algorithm, line Power Flow, Particle Swam Optimization.
