Embodiment Construction
[0052] An optimization method for power flow calculation of an active distribution network, comprising the following steps:
[0053] S1: Active distribution network can be regarded as containing n b A simple system diagram of a node and M branches. The radiation operation of the distribution network requires that all nodes be connected and there is no closed loop, so it comes down to the concept of "tree" to illustrate this problem. The definition of "tree" in the electrical network theory is: a tree T of a connected graph G contains all the nodes and some branches of G, and the tree T itself is connected and does not contain loops. At the same time, one with n b A connected graph of nodes, the number of branches of any tree of it is formula (1):
[0054] M=n b -1 (1)
[0055] The network structure of the active distribution network can form a radial operation structure according to the concept of "tree". According to the above analysis, it can be concluded that the radia...
