Recently, analysis of some major blackouts and failures of power system shows that voltage instability problem has been one of the main reasons of these disturbances and network collapses. In this article, a systematic approach to voltage stability analysis using various techniques for the IEEE 14-bus case study is presented. Static analysis is used to analyze the voltage stability of the system under study, while the dynamic analysis is used to evaluate the performance of compensators. The static techniques used are power flow, V-P curve analysis, and Q-V modal analysis. In this study, Flexible Alternating Current Transmission system (FACTS) devices-namely, static synchronous compensators (STATCOMs) and static var compensators (SVCs)-are used as reactive power compensators, taking into account maintaining the violated voltage magnitudes of the weak buses within the acceptable limits defined in ANSI C84.1. Simulation results validate that both the STATCOMs and the SVCs can be effectively used to enhance the static voltage stability and increasing network loadability margin. Additionally, based on the dynamic analysis results, it has been shown that STATCOMs have superior performance, in dynamic voltage stability enhancement, compared to SVCs.

“…Other works on dynamic analysis can be found in Ref. 10 Induction generators need reactive power to operate-thus they draw it from the grid unless fitted with a local reactive power source. On the other hand, the doubly fed induction generator (DFIG) or the synchronous generator can regulate their own power factor from leading to lagging.…”
