Application of the Search Forward and Backward Substitution Method Based on the Adjacency Matrix in the Flow Calculation

This paper analyzes the characteristics and calculation methods of the existing network-based structure of the distribution network,and proposes a hierarchical search method based on the adjacency matrix between nodes for calculation of the load flow of the distribution network.This method does not need prior analysis and or the definition of the slip road.With the layered matrix of nodes obtained through hierarchical search of the adjacency matrix,the hierarchical matrix can assign the branch node to complete definition of the slip.Identification of the topology of the radial distribution network can be efficiently realized quickly,and practical flow calculations can be conducted.This entire programming process is simple,clear,and practical.The use of sparse vector operation means and technique helps to improve the running speed.The proposed method is proveds to be effective through simulation.
