A PRACTICAL ALGORITHM OF LOAD FLOW CALCULATION FOR DISTRIBUTION NETWORKS

On the basis of analyzing the features of distribution network structure and the merits and drawbacks of existing load flow calculation method for distribution network, a superposition principle based algorithm of load flow calculation for distribution network is put forward. In this algorithm the topological network structure is described by the admittance matrix of nodes. Different from the forward- and backward-substitution method widely used in load flow calculations of distribution networks, in this algorithm the complicated numbering of nodes is not necessary and the presented algorithm is applicable to the load flow calculation for the distribution networks operated in weak mesh network. This algorithm is simple and direct and possesses good convergence. The results of calculation examples show that this method is effective.
