There is a new characteristic for the distribution network that it is incorporated with distributed generations (DC). Some simplifications and assumptions were made for the DC's constant power model and random power model, and the effects of island operation of distributed generation system were considered on the distribution network reliability after the distribution network fault. The network hierarchical delaminating and subarea model was improved in network partition method, so that this method is applicable to the distribution network reliability assessment with Preliminary consideration DC The proposed method was tested by a typical distribution system, which shows the efficiency of the method. The result shows that DC can increase the reliability of distribution system.
