The complexity due to massive growth of power systems has to increased demand of electrical energy giving rise to numerous stability challenges. In these situations, Flexible Alternating Current Transmission System (FACTS) controllers have increasing been applied. This paper discusses and compares the transient stability enhancement by use of SSSC and IPFC FACTS controllers when applied in Transient Stability Enhancement (TSE) in a dynamic IEEE 14 bus system with fault applied at bus 04. It is achieved by observing the behavior of damping power oscillations. Time domain responses for angular frequencies and voltages responses have been analyzed.
