摘　　要： 分布式电源具有经济、高效、灵活、环保等特点,有着良好的发展前景和商用价值。在分析了分布式电源(DG)接入配电网的3种方式及分布式电源的3种等效模型的基础上,提出了计及分布式电源的配电网供电可靠性评估计算模型,采用改进的最小路法对1个典型的配电网系统进行计算,并与加入DG之前的配电网可靠性指标进行了对比分析。研究结果表明,所提出的模型和算法适用于DG接入配电网的供电可靠性评估。 The distributed generation（DG） not only has characteristics such as economy,high efficiency,flexibility,environmental protection and so on,but also has good development prospect and commercial value.This paper analyses three ways of distributed generation accessed distribution network and three equivalent models of the distributed generation,based on this,the power distribution reliability evaluation calculation model of distribution network which has distributed generation is put forward,the improved minimal path algorithm to calculate a typical distribution network system,analysed and compared with the reliability index of distribution network without DG.The research results show that the model and algorithm suggested by this paper is suitable for power distribution reliability evaluation of distribution network which has DG.
