Abstract

Power system is facing new challenges as the present system is subjected to severely stressed conditions. Voltage instability is a quite frequent phenomenon under such a situation rendering degradation of power system performance. In order to avoid system blackouts, power system is to be analyzed in view of voltage stability for a wide range of system conditions. In voltage stability analysis, the main objective is to identify the system maximum loadability limit and causes of voltage instability. Static voltage stability analysis with some approximations gives this information. Voltage stability problem is related to load dynamics and therefore dierent load characteristics are to be considered in the voltage stability analysis.
