| 摘 要： | 为了更好地应用分布式电源（DG），微网受到越来越多的关注，因此有必要对微网接入后配电系统的可靠性进行评估。本文应用光伏发电、风电、微型燃气轮机和储能等分布式电源构建微网，建立可靠性分析模型，并提出适用于含微网配电系统的新型可靠性指标。利用最小路法，按照不同方案对某辐射型配电系统进行可靠性评估，在评估中考虑了重要负荷的因素。结果表明，微网的接入可提高配电系统的可靠性，微网的接入位置、容量等也会对可靠性产生较大的影响。当考虑了重要负荷时，微网的效益更加显著。

| Abstract: | In order to make better use of distributed generators (DG), micro grids are getting more and more notice. So, it is necessary to assess the impact of micro grid on distribution system reliability. The PV, WT, micro gas turbine and energy storage are applied to build micro grids and its reliability analysis model. Besides, some new reliability index has been proposed to assess the distribution system with micro grids. By using minimal path method, this article assesses the reliability of a radiant power distribution system based on different alternatives. The factor of important loads has been considered. The results show that micro grids can raise the distribution system reliability; the location and capacity of micro grids have an obvious influence on the reliability; the benefit of micro grids is more notable when the factor of important loads are considered. |
