A new topology structure and load flow solution for radial distribution networks

In this paper an efficient power flow solution with topology analysis is studied to support distribution network reconfiguration techniques in practice use. A new topology model is proposed which defined as a tree node data structure to describe the connecting relationship among the nodes dynamically. The depth-first search strategy with node storage queue technique is also used to form the tree structure rooted from the supply node. The forward and backward sweep process is accomplished with the help of the tree traversal technique. The application of recursive equations makes the program simple and concise. Numerical results are presented to illustrate the effectiveness of the proposed method.
