Study of Shunt FACTS-Based Controllers Effectiveness on Multi Machine Power System Steady State Operation

The continuous change in power demand and supply altered the power flow patterns in transmission networks in such a way that some of the corridors are lightly loaded and some of the corridors get over loaded. This raises serious challenge in operating the power system in secure and reliable manner. To cope with this problem Flexible AC Transmission Systems (FACTS) is used. It plays a very important role in improving the power system operating performance. In this paper load flow models for STATCOM and SVC have been developed. Power flow study of a five bus system is carried out with and without FACTS controllers. Results of the power flow studies are obtained with MATLAB programming.
