Abstract

Location of shunt compensation devices is important for the enhancement of the voltage stability for practical power systems. This paper presents a comparison of several voltage stability indices in electric power system to identify the weakest bus/ area of the system. Shunt FACTS controller is introduced at the weakest bus in IEEE 14-bus test system and its effectiveness is assessed by comparing voltage profile and loading margin enhancement. Various line stability indices are also compared with and without shunt FACTS controller. It is shown that the best location for reactive power compensation for improving static voltage stability margin is the "weakest bus" of the system.
