借鉴大电网脆弱性的定义，考虑微电网数学模型和元件的可靠性参数，提出加权复杂网络参数及微电网节点和线路运行综合灵敏度，形成微电网脆弱性评价体系，在此基础上建立考虑联网/孤岛两种运行模式的微电网重构数学模型。模型以微电网综合脆弱度最小为目标函数，选取美国微电网CERTS为算例，采用搜索矢量拟态物理学（SV-APO）算法进行优化计算。结果表明所述模型能根据微电网固有的网络结构参数和运行状态及时正确地给出微电网的重构及运行方案，可为日后微电网安全运行维护及改造提供参考。

Taking mathematical model of the microgrid and reliability parameters of the components into account, this paper proposes two vulnerability assessment indexes-weighted complex network parameter and nodes-lines comprehensive sensitivity to set up a vulnerability assessment system of the microgrid. Finally the microgrid reconfiguration model considering the grid connected/island mode and vulnerability assessment indices are built. Taking CERTS system as an example, the model in this paper is calculated by using search vector artificial physics optimization(SV-APO) algorithm to minimize the system vulnerability. The result shows that the model is able to provide a correct and effective reconfiguration solution and the operation mode based on the structure parameters and the state parameters of the micro-grid after fault.
