摘要：

In reliability evaluation of distribution networks containing microgrids, two methods, namely simulation and analysis, are widely used. However, simulation method costs too much computation time because of its poor convergence, and analytical method is difficult to deal with time-varying process. To solve these problems, this paper proposed a new analytical method to evaluate reliability of distribution network containing microgrids. The concept of power interruption sequence is defined and its multi-state model is proposed to evaluate hosting customers' outage situation. A calculation method for probability of power interruption sequence is proposed based on forward algorithm and multi-state model. Based on multi-state model of power interruption sequence and traditional analytical algorithm, a new analytical algorithm is put forward. Case studies show that, compared with simulation method, the proposed algorithm can reduce about 98% computation time with high accuracy. In addition, sensitivity analyses of capacity influence of wind, photovoltaic and energy storage on reliability are conducted. © 2019, Power System Technology Press. All right reserved.
