An efficient distribution load flow method for radial distribution systems with load models

Abstract

In this paper a novel efficient approach is modelled for load flow problem in distribution systems based on the distinctive topological characteristics of radial distribution networks and have been fully studied to make the direct solution possible. Due to the direct solution of the proposed method, the usage of time-consuming decomposition or bus admittance matrix in the traditional load flow methods are no longer necessary. The Branch Path Distribution Load Flow (BPDLF) algorithm needs less memory for any size of the distribution network because it uses only branch path matrix in its algorithm. Due to this it has faster convergence with less iterations. The effectiveness of the proposed method is validated on various standard IEEE test systems for different load models and compared with existing algorithms. The future load growth on various IEEE systems are also studied. Test results reveal that the proposed method is better when compared with existing algorithms.
