Low voltage reliability equivalent using monte-carlo simulation technique

Abstract

Reliability is the ability of a system to supply continuous electricity to customer which ends with zero fault that occurs under a specific period of time. Most of the literature focus more on medium voltage (MV) and high voltage (HV) compared to the low voltage (LV) due to the general absence of exact data in LV network and sizing of LV network. In addition, an increament in size of the LV network makes the network more complex and difficult to assess. Therefore, in this paper, the performance of reliability in LV network will be evaluated in detailed network model. To reduce simulation time, methodology of reducing detailed network into an equivalent network is introduced. This equivalent network is obtained by simplifying the complex network using Monte-Carlo Simulation technique. The results in this research are quantified and compared between these detailed and equivalent networks in reliability indices; SAIFI, SAIDI and CAIDI. The values of SAIFI, SAIDI and CAIDI in detailed network are slightly higher than in equivalent network.
