Radial power distribution network load flow calculation method and device based on improved incidence matrix

According to a radial power distribution network load flow calculation method and device based on the improved incidence matrix, for the topological structure of the radial power distribution network,a breadth-first search method is used for renumbering network nodes, the improved incidence matrix is created according to original node numbers and new node numbers, and on this basis, forward-backward sweep load flow calculation is carried out, so that the frequency of reading the incidence matrix elements during algorithm iterative calculation is reduced, the memory occupied by the algorithm is reduced, and the load flow calculation speed is further improved. 本发明提供的一种基于改进关联矩阵的辐射状配电网潮流计算方法及装置，所述的计算方法针对辐射状配电网的拓扑结构，利用广度优先搜索法对网络节点重新编号，依据原始节点编号和新节点编号创建改进的关联矩阵，在此基础上，进行前推回代法潮流计算，减少了算法迭代计算时读取关联矩阵元素的次数，同时减少了算法占用的内存，进而提高了潮流计算的速度。
