摘要
为有效地进行电网输电断面的搜索,提出基于复杂网络理论的电网分区及输电断面搜索方法。首先,根据GN算法对电网进行分区,对其无法避免的3台及以上串供结构进行检测和修正,以模块度为指标确定最优分区方案,搜索分区断面;其次,根据最小割集思想,基于Karger方法对分区断面进行搜索,获取电网的输电断面。所提方法在新英格兰39节点和某地区实际电网中的应用验证了其搜索输电断面的有效性。
In order to search the transmission section of the power grid effectively,a power grid partition and transmission section searching method was proposed based on the complex network theory. Firstly,the power grid partition method was proposed according to GN algorithm,and collusion structure of three or more transformer substations was detected and corrected. The best partition scheme was determined by its modularity,and then searched partition sections. Secondly,according to the minimum cut set theory,Karger method was used to search the transmission section based on the partition sections. Last,the proposed method was applied in the 39 bus New England system and an actual power grid to verify its effectiveness of searching transmission section.
