| 摘要: |
| 提出了一种改进的含微电网的新型配电网供电可靠性指标计算方法。该方法计及因电压骤降、骤升引起的敏感复合停运频次及累计停运时间，克服了可靠性指标常规计算方法的不真实性。分析了基于最小路的负荷点可靠性评估方法和多元复合储能系统提高配电系统整体供电可靠性的机理，制定了正常、故障情况下的充放电策略，在此基础上提出了多元复合储能系统容量配比计算方法。IEEE可靠性测试系统的仿真结果，验证了所提方法的正确性与有效性。 |

| Abstract: |
| An improved calculation method of power supply reliability index is proposed for the distribution network with microgrid，which considers the frequency and cumulative time of sensitive composite outages caused by voltage swell and sag to improve the authenticity of traditional reliability index calculation methods. The method of load point reliability evaluation based on the minimal path algorithm and the mechanism of distribution system overall power supply reliability enhancement by the multi-element composite energy storage system are analyzed，based on which，the charging／discharging strategies under normal and fault conditions are worked out and the capacity configuration calculation of multi-element composite energy storage system is proposed. The simulative results of IEEE reliability test system show the correctness and effectiveness of the proposed method. |
