Voltage sag calculation based on Monte Carlo technique

Fault occurrence in power system not only affects on reliability of system but also stability too. In many cases, fault occurrence in power system leads to voltage depressions -dips or sags- that damages to power system components. In this paper, using stochastic technique in appropriate modeled power system simulated in PSCAD/EMTDC software, maximum voltage sag will be calculated based on the Monte Carlo technique. The results show that the presented technique has excellent ability in order to detect and estimate the amplitude of voltage sags in different conditions.
