Abstract
This paper analyzes the application of Bifurcation techniques in the investigation of voltage stability of a dynamic power system. Voltage stability analysis of a power system is necessary during the planning and operating stages of the power system. In the modern scenario where the power system is almost operated near to the stability margin, analysis of the voltage stability is obligatory. Bifurcation theory which holds good for voltage stability analysis has been applied to the IEEE 14 test bus system with dynamic components. The Continuation Power Flow (CPF) and Eigen value analysis was carried out. Initial studies showcase the existence of Saddle Node Bifurcation (SNB) and Hops bifurcation in the test case system. In order to improve the stability of the system Static Var Compensator (SVC) was introduced in the test bus system and the results shows a significant improvement in the voltage stability of the power system.
