چکیده
Voltage stability analysis is the major concern in order to operate any power system as secured. In this context there are many research work has been carried out to improve the voltage stability. This study demonstrates the use of latest Power System Analysis Toolbox (PSAT) package for network analysis of alternative means of improving existing transmission system voltage stability. This paper presents the investigation on enhancement of voltage stability using FACTS controllers such as Static Var Compensator (SVC) device. The proposed method explains how voltage stability can be improved with the continuation power flow methods in case of increasing loading of contingency. Voltage stability assessment on standard IEEE-14 system has been simulated to test the effectiveness of increasing loadability. This paper presents the simple method for identifying the weak bus and also optimal value of reactive power support needed for that. A comparative study between the base case and SVC are presented to demonstrate the effectiveness of SVC. The propose methodology found advantages because it is simple, faster and very convenient to apply for voltage stability analysis
