| 摘要: |
| 为分析微电网各种运行模式尤其是非计划解列运行情况下对配电网中负荷点可靠性的影响，提出一种基于改进故障模式与后果分析法的含微电网的配电网可靠性评估算法。在可靠性的评估过程中，建立开关因子模型和分区简化模型，降低含微电网的配电网的网络复杂性，减少可靠性分析的计算量；对传统的配电网潮流算法进行改进，使之适用于微电网的不同运行模式。算例仿真结果验证了所建模型的有效性，分析结果表明，微电网对配电网中不同负荷点的可靠性的改善效果具有差异性，且在提高负荷点可靠性参数方面具有选择性。 |

| Abstract: |
| A method of reliability evaluation based on the modified FMEA（Failure Mode and Effect Ana-lysis） is proposed for the distribution network containing microgrid，which analyzes the impact of the operational modes of microgrid，especially its unintentional splitting operation，on the reliability of load points. The switch factor model and simplified zone model are built during reliability evaluation to reduce the complexity of distribution network containing microgrid and the computational load of reliability analysis. The traditional distribution network power flow algorithm is improved to adapt different operational modes of microgrid. Results of case simulation show the effectiveness of the built models and analysis proves that，the impacts of microgrid on the reliability improvement of different load points are different and its effects on different reliability indexes of load point are different as well. |
