摘　　要：并行恢复对加快大停电后系统的恢复具有十分重要的意义,而恢复子系统的合理划分是并行恢复的基础,但到目前为止在理论上还没有成熟的方法来指导恢复子系统的划分。在此背景下,提出了一种新的基于复杂网络社团结构理论的恢复子系统划分算法。该算法根据黑启动机组在电网中的分布情况以及电网自身特点来划分子系统,利用模块度指标来衡量划分结果的合理性,并根据各个子系统分裂出来的先后次序来确定子系统之间同步并列的先后次序。克服了传统方法无法衡量划分结果合理性、不能适当确定同步并联规则或策略的缺点。最后,以新英格兰10机39节点系统为例说明了所述方法的基本特征。The bottom-up strategy is one of the most important and indispensable restoration approaches for ensuring fast power supply restoration to end users. Reasonably dividing restoration subsystems is an essential step for speeding up the restoration procedure with the bottom-up strategy. Based on the community structure of the complex network theory, a new algorithm for dividing restoration subsystems is proposed. The locations of black-start units and the characteristics of the power grid are taken into account in the algorithm. Then, the modularity index is employed to evaluate the rationality of the division results, and the sequence of interconnecting the subsystems could be determined accordlng to the sequence that every subsystem separates from the system in the divisive process. Some problems existing in the traditional methods, such as how to evaluate the rationality of the dividing results and how to sequentially interconnect the subsystems, could be solved by using the proposed algorithm. Finally, the New England 10-unit 39-bus system is employed to illustrate the essential features of the proposed algorithm.
