Paper Title
Dynamic Voltage stability of Power Systems
  Abd-Rabbou Ibrahim Hasan El-Sinnary,  Mohammed Ibrahim El-Sayed,  Abd-El-Reheem E.A. Mostafa

Voltage stability is one of the most important problems faced in power systems. Recently, a lot of studiousness has been paid to the subject of dynamic voltage stability. It is well known that induction motor loads have a particularly significant impact in the voltage stability. This paper investigates the effect of the increasing load on the bus, and studies the effect of Flexible Alternating Current Transmission Systems (FACTS), whether Static Var Compensator (SVC) or Static Synchronous Compensator (STATCOM) on dynamic voltage stability of a power system. The Critical fault Clearing Time [CFCT] of the system due to startup of induction motor, to prevent voltage instability has been analyzed. Comparative performance assessment for SVC and STATCOM has been examined. A Power System Analysis Toolbox (PSAT) using MATLAB Program is used to calculate voltages with Time and Critical Fault Clearing Time at each bus for IEEE 9 bus systems.

Keywords- Dynamic Voltage Stability, SVC, STATCOM, CFCT
