Modern power systems are operating under much stressed conditions and this is making the system to operate closer to their operating limits. Since a couple of decades ago voltage stability assessment has received an increasing attention due to the complexity of power system. With the increase in power demand and limited power sources has caused the system to operate at its maximum capacity. Therefore, a study that is able to determine the maximum capacity limit before voltage collapse must be carried out so that necessary precaution can be taken to avoid system capacity violation. This paper discuss a Voltage Stability Index (VSI) for IEEE 30bus system. Voltage stability indices (VSIs) are very vital to voltage stability assessment; they have several areas of application such as distributed generation (DG) placement and sizing, detection of the critical regions, lines, and buses and contingency ranking and planning. These indices can be used to activate countermeasures against voltage instability. The Voltage stability indices is indicative in predicting the occurrence of system collapse and hence necessary action can be taken to avoid such incident. Here simulation of VSI has been done for IEEE 30-bus test system to identify more sensitive method to detect the weakest line of the system.
