In this paper

the issue of reliability evaluation of active distribution network（ADN） containing typical distribution power supply is studied. In view of random fluctuation feature of the source-load side resources

a kind of mathematical model for the reliability evluation of active distribution system based on antithetic variable sampling Monte-carlo algorithm is proposed. Firstly

the probabilistic index modeling of randomn source-load side resources is established

then the reliability evaluation index for the typical distribution network is set up for evaluating the influence of distribution power supply after connection on the reliable operation of the distribution system. After that

the antithetic variable sampling techniques is introduced to improve the drawback of traditional Monte-carlo algorithm in the treatment of calculation efficiency of reliabiity evaluation method and thus improve the variance accuracy of the calculation result. Finally

the main feed F4 of improved IEEE-RBTS Bus 6 is analyzed and calculated to verify both the feasibility of the modeling in the paper and high efficiency of the proposed algorithm.
