摘　　要：含有分布式电源的配电网在我国电网所占比重正逐年提高,为了提高分布式电源利用率,有必要对含有微电网的配电系统性能进行评估。因此,文章针对含有风力发电、光伏发电以及微型热力发电的分布式电源微电网构建了出力和负荷模型,提出基于最小路法的含微电网配电系统可靠性评估算法,以改造后的辐射性配电系统为例,对系统内各负荷点进行综合评估,验证了评估算法的有效性。In order to improve the utilization of distributed power,it is necessary to evaluate the performance of the distribution system with the micro-power grid.Therefore,this paper constructs the output and load model for the distributed power supply micro-power grid which contains the wind power generation,the photovoltaic power generation and the microthermal power generation,and puts forward the system reliability evaluation algorithm of the micro-grid power distribution system based on the minimum road method,taking the modified radiation distribution system as an example.The load points in the system are comprehensively evaluated,and the effectiveness of the evaluation algorithm is verified.
