Abstract


Nowadays the biggest challenge of the electrical power transmission system is voltage collapse. As a result, these days a major outlook has been paid with the aid of a variety of research on voltage stability. In this paper, a method has been introduced to determine the voltage stability of an IEEE 14-bus power system. This technique is based on Reactive Power Sensitivity Indicator. Using this indicator, weak buses are identified among the 14 buses of the system under study. Newton-Raphson method of Load Flow Analysis is coded in MATLAB programming to find out different parameters of the IEEE 14-bus system and used for stability analysis. A FACTS device has been installed in the weakest bus to enhance the voltage stability of the network. The results exhibit the effectiveness of the proposed technique.
