| 中文摘要: |
| 未来某一时刻的微电网运行状态和脆弱程度作出准确评估，有利于发现薄弱环节，实现系统自愈运行。基于微电网模型与特性，提出基于风险理论的微电网脆弱性预评估方法。首先对微电网脆弱性进行定义，其次根据微电网各脆弱事件发生的概率及造成的后果严重度，建立微电网脆弱性预评估指标体系，包括发电容量充裕度和系统供电脆弱性两大类，最后建立微电网预评估的流程步骤，并通过算例验证评估指标的有效性及合理性。 |

| Precise assessment of the operation and vulnerabil.ity in microgrid at a certain time in the future contributes to find outthe weak point in the system in time and realize self.healing opera.tion of microgrid.Based on the characteristics of microgrid, a vulner.ability pre.assessment method for microgrid is proposed.Firstly, thedefinition of microgrid's vulnerability is given.Then, according tothe occurrence probability of every influential event and severity ofcorresponding results, a vulnerability index system is established,mainly including indices of generation capacity adequacy and indi.ces of power supply vulnerability.Eventually, the procedures andspecific steps of vulnerability pre.assessment for microgrid are pre.sented, and its effectiveness and validity is verified by case studies. |
