Abstract:

The current deregulated power system structure demands stability, accuracy and rapid response day by day. The protection and reliability of the electric power system cannot be compromised by voltage instability. Flexible AC transmission system (FACTS) are therefore used with weak buses to recover and control voltage. Static Synchronous Compensator (STATCOM) and Static Var Compensator (SVC) provides fast working dynamic compensation when a significant fault arises. This article presents the enhancement of stability of voltage by minimizing the deviation of voltage of the 14-bus system of IEEE as a test system. For this, the SVSI index is used with STATCOM and SVC.
