Weakest location exploration in IEEE-14 bus system for voltage stability improvement using STATCOM, synchronous condenser and static capacitor

In modern power systems, long transmission lines coupled with fast-growing load demand factor have resulted in a more stressed system than ever before. This paper is aimed at static voltage stability analysis(VSA) of IEEE-14 bus standard test case for weakest region exploration using conventional P-V and Q-V curve methods for investigating voltage unstable regions, predicting and preventing system blackouts. Furthermore, the static capacitor, synchronous condenser and STATCOM have been used for effective voltage restoration and regulation purposes. Hence the power grid can effectively manage and provide electricity reliably, safely and economically to consumers. Power World Simulator environment has been used for performance analysis.
