In today's scenario, as the development is taking place simultaneously the demand for the electricity in the world is also increasing. Operation and planning of large interconnected power systems are becoming more and more complex. In power system, voltage stability plays a very important role. Voltage instability may cause blackouts and collapse of the power system. In last decade, many countries have experienced the problem of blackouts due to voltage instability. The problem of voltage stability is mainly caused due to stressed loading condition of the system. It is essential to analyse the voltage stability for improvement in the efficiency of power system. Various authors have conducted research on analysis of voltage stability and methods to improve it. This paper, presents a review on research and development in the voltage stability analysis and methods for improving the voltage stability.

“…También se probó la efectividad de los índices de estabilidad para predecir la severidad de las contingencias (Limbu et al, 2005). En el 2006 se analizaron y se compararon índices de sensibilidad, singulares, modales, estabilidad de línea y de voltaje en los nodos, para diferentes incrementos de carga (Reis y Barbosa, 2006). En el 2006 se evaluaron varios índices de predicción del colapso de voltaje dinámico, tales como: proximidad al colapso de voltaje, líneas de transmisión y de margen de potencia, y estabilidad de transferencia de potencia (Muhammad Nizam et al, 2006).…”

“…Several methods have been used for static voltage stability analysis such as the P-V and Q-V curves, modal analysis, etc. [2]. Line voltage stability indices (LVSI) provide important information about the proximity of the system to voltage collapse and are also used to identify the critical line of the system [3].…”

Voltage stability issues have attracted the interest of power system researchers worldwide. It is important to maintain the system stability, or else it would lead to voltage collapse and consequently complete blackout of the system. In this paper the voltage stability indices, Fast Voltage Stability Index (FVSI) and Voltage Reactive Power Index (VQI Line ) are used to determine the stability of a system. These indices are used to identify the most critical line and bus of the system. Under single line outage condition, effect of placing a TCSC in the system on FVSI & VQI Line has been observed. An IEEE 6 bus system has been considered for simulation purpose.
