A hybrid method of reliability evaluation for distribution system based on the least distribution section and Monte Carlo simulation method is presented in the paper. According to the characteristics of integrity and the same results of their failure

the distribution network is divided into sections

and the simplified network model is created based on the least distribution section. The probability distribution indices of the system and every load point are obtained by the use of Monte Carlo simulation method based on the simplified network model. Through evaluating RBTS-BUS6 system using the proposed algorithm

the results show that this method is practical

feasible.
