1.For optimal placement of phasor measurement units(PMUs), i.e., determining the least number of synchronized PMUs to be placed and their optimal positions to reach the maximal observability of the network structure, a minimum spanning tree (MST) algorithm is proposed. A new optimization rule is put forward based on depth-first search (DFS) algorithm, thus the quality of solution and calculation speed are improved.
针对确定配置同步相量测量单元(PMU)的最小数目和最佳位置以达到最大的网络结构可观测性的PMU最优配置问题,提出了一种最小生成树(MST)算法,在深度优先搜索(DFS)算法的基础上提出了一种新的寻优规则,从而提高了解的质量和求解速度。收藏指正
