Determination of Optimal Placement Point for Voltage Stability Using SSSC in Power System

Abstract

Voltage Stability is defined as the relationship between the bus voltage and the maximum load parameter value depending on the operating condition of the system. The placement of Flexible Alternating Current Transmission System (FACTS) devices in the appropriate places increases the operating limits of the system in terms of voltage stability. In this study, the effects of Static Synchronous Series Compensator (SSSC) in IEEE 14 bus power system were investigated. The voltage and the maximum loading parameter relationships of the SSSC which is connected to different transmission are interpreted. Furthermore, the effects of SSSC on the bus voltage profile have been investigated. The study on the multi buses power system was analyzed in the Power System Analysis Toolbox (PSAT) program. As a result of the study on IEEE 14 bus power system, the loading parameter value has been increased when the SSSC is connected to all transmission lines. In particular, it has been observed that the best results are obtained by connecting SSSC in transmission lines 2-3.
