摘要:
针对电压控制的电网分区数量难以确定和分区易发生改变的问题,提出了一种基于矩阵摄动的谱聚类方法。该方法在谱聚类算法上,通过电气距离构造网络的Lapiacian矩阵,利用其特征根变化量确定分区数量,最后使用k-means聚类算法对电网进行分区。在IEEE14节点的仿真系统下,该方法与原来的分区数和分区结果相同;而IEEE39节点的测试系统的空间电气距离和节点联系紧密度,具有一定的鲁棒性,通过蒙特卡洛随机模拟,在扰动较小的情况下,该方法的分区数保持不变,而在较大扰动下,分区数可能会发生改变,但变化的概率很小。
Abstract:
According to the problem of grid partition for voltage control that numbers were difficult to determine and partition easily changed, it put forward the Spectral clustering method based on matrix perturbation. This method used the electric distance of structure networks Lapiacian matrix and its eigenvalue variation to determine the number of partition, and then system were divided by k-means algorithm. The result of IEEE-14 bus test system simulation is the same with the original partition. Besides, Research on electric distance and tightness of buses for IEEE-39 bus test system simulation shows that the algorithm has some robustness and through the Monte-Carlo, partition numbers remain the same under small disturbance while the probability of changed partition numbers under large disturbance is small.
