Steady state and transient problems in a power system have undesirable consequences on the system. It can limit the amount of power that can be transmitted in the system and consequently leads to voltage instability and at times it may also result into total voltage collapse. This paper is a comparative investigate in enhancement of voltage stability via Static Synchronous Series Compensator (SSSC) and Static Var Compensator (SVC) externally controlled by a Power Oscillation Damping (POD) controller. The new designed P.O.D controller is very efficient for voltage stability under transient conditions.
