FACTS Controllers Impacts on Security Margin Enhancement in Power System

Payam Farhadi, Tina Sojoudi, Shabnam Zabihi, and Mohammad Karimi

Abstract—In this paper, voltage stability of power system has been investigated in the presence of three types of FACTS controllers including SVC, STATCOM and UPFC. Voltage stability and voltage collapse point and the loading amount are calculated with and without FACTS controllers. Simulations have been carried out on 33-bus network test system in PSAF software. It was found that without the installation of FACTS controllers, the maximum loading amount is 1.71 (p.u), which by installing any of these FACTS controllers and changing their installation place, loading value is also changed. In this paper, the installation of various types of FACTS controllers has been examined simultaneously as well as by installing several numbers of just one of these FACTS controllers.

Index Terms—Voltage stability, FACTS controllers, security margin, continuity power flow.
