Monte Carlo simulation-based reliability studies of a distribution test system

This paper presents the results of a Monte Carlo simulation (MCS) approach to the Roy Billinton distribution test system (RBTS). The paper presents the load point reliability indices and system performance indices using the MCS method for five distribution system-buses 2, 3, 4, 5 and 6 of the RBTS. Four possible probability distributions of times to repair (TTR) and times to switching (TTS) of components are incorporated in the simulation studies. The cumulative probability distributions of system performance indices such as SAIFI and SAIDI for the four different distributions of TTR and TTS are also presented. The results obtained by the simulation method are compared with those available for the RBTS using an analytical approach. The study results show that the simulation method gives acceptable reliability indices and can also be used to provide information on the probability distributions associated with the predicted indices for different distributions of TTR and TTS.
