Abstract: This paper presents an alternative approach to evaluate voltage stability indices in electric power systems by using Monte Carlo simulation (MCS). Fast voltage stability index (FVSI), line stability index (Lmn) and line stability factor (LQP) are used as indicators to determine the capability of reactive power loading at a given bus position. Conventionally, loading the test bus with pure reactive power is not realistic because power system load changes randomly at every load bus in both real and reactive powers. In this paper, MCS was introduced to simulate load increment of all load buses with appropriate random numbers and their probability. From this approach, all the indices mentioned above can be calculated repeatedly with a large number of trials. To evaluate its use, a small five-bus, and the standard IEEE 30- and 57-bus test systems were employed for demonstration. As a result, comparing among these indices, the weakest bus of the test system can be identi!
fied with some degree of confidence.
