A sequential numbering power flow calculation method for distribution network

As distribution network is of radial pattern, the forward and backward substitution algorithm and its variations are widely used for radial distribution network power flow calculation, which needs to form associated admittance matrix and matrix operations. This paper proposes a sequential numbering power flow calculation algorithm for distribution network. Based on the graph theory of nodes, the proposed method can handles multiple branches radiation network. In the simulation test, our proposed algorithm is applied to a typical radial distribution network in order to verify the efficacy on power flow calculation. The results show that the sequential numbering power flow algorithm has good performance in terms of convergence rate and reliability. © (2014) Trans Tech Publications, Switzerland.
