| 摘要: |
| 大停电事故发生后若系统内含有多个黑启动电源，合理的子系统划分方案将有助于各系统协调并行恢复进而缩短恢复时间。建立以子系统间联络线最少为目标的子系统划分的整数线性规划模型；通过构造“割”约束并利用高效求解器CPLEX对模型多次求解以获取足够多的方案；建立子系统划分方案的评价指标集，并采用变异系数法对方案进行综合评价和排序；引入摇摆节点的概念对模型进行预处理，降低决策空间规模。新英格兰10机39节点系统和IEEE 118节点系统的子系统划分结果验证了所提模型和方法的有效性。 |

| Abstract: |
| If there are several black-start units in the system after blackout, a reasonable subsystem division scheme will help sub-systems be restored in parallel and shorten the restoration time. An integer linear programming model for subsystem division is established, which takes the minimize number of tie lines between sub-systems as its objective. The “cut” constraint is constructed and the high-efficiency solver CPLEX is adopted to solve the model several times for obtaining abundant schemes. The evaluation index set of subsystem division schemes is set up, and the varia-tion coefficient method is used to comprehensively evaluate and sort the schemes. The concept of swing node is introduced to pre-process the model for reducing the size of decision space. The subsystem division results of New England 10-machine 39-bus system and IEEE 118-bus power system verify the effectiveness of the proposed model and method. |
