چکیده
Voltage stability analysis is essential for a secure power system operation.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 project presents the investigation on steady state voltage stability improvement by determination of best location of Flexible ac transmission system (FACTS) controllers such as Static Compensator (STATCOM) device with minimum losses. The proposed method explains how voltage stability can be improved with the continuation power flow (CPF) method in case of increasing loading of contingency. Continuation power flow analysis which is currently used for evaluation of location of weak buses/areas of the power system sensitive to load increase. Voltage stability assessment on a 6-bus system has been simulated to test the effectiveness with increasing load. A comparative study of 6-bus test system between the base case and with Static Compensator is presented to demonstrate the effectiveness of Static Compensator. The proposed methodology found advantages because it is simple, faster and very convenient to apply for voltage stability analysis.
