随着微网相关技术的不断成熟，制定完整的微网供电可靠性评估体系已经成为了最为重要的理论研究环节之一。在故障模式分析法和蒙特卡洛模拟法的基础上，提出了一种计及微电源出力随机特性的可靠性指标计算方法，并利用该方法对某算例系统的系统可靠性指标和用户可靠性指标进行了计算。在此基础上，引入负荷分级机制，分析了不同分级方法下用户和微网系统的可靠性指标的变化，并对微网负荷分级模式提出相关建议。

With the smart grid related technologies becoming more and more mature,formulating a complete system of microgrid reliability evaluation has become one of the most important theoretical research topics.Based on the failure mode analysis and Monte Carlo simulation method,this paper puts forward an algorithm of evaluating microgrid reliability indexes considering the influence of the random characteristics of microgenerator output.With this algorithm,the reliability indexes of load points in microgrid and of the whole microgrid system are both described.Based on it,the mechanism of load classification is introduced,and the variations about reliability indexes of customers and microgrid system in different classification methods are analysed.On that basis,some load classification modes are recommended.
