英文摘要：

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 an- tithetic variable sampling Monte-carlo algorithm is proposed. Firstly, the probabilistic index modeling of ran- domn 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 relia- ble 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.
