A loop based load flow method for weakly meshed distribution network

Abstract

A distinctive load flow solution technique is proposed for the analysis of weakly meshed distribution systems. The special topological characteristics of distribution networks have been fully exploited to make the solution possible. A branch-injection to branch-current matrix is formed (BIBC). This matrix is obtained by applying Kirchhoff’s current law for the distribution network. Using the same matrix a solution for weakly meshed distribution network is proposed. Bus voltages are found by forward-sweep of the network. Test results of 33-bus and 69-bus systems are given to illustrate the performance of the proposed method.
