The Load Flow Approach for Radial Network Distribution Systems Based on Network Topology

Abstract

The distribution power flow is a significant tool for distribution system analysis. It's employed both in the operational and planning levels. The recent trend toward distribution automation has shifted the attention to load flow solutions that are both reliable and efficient. The problem of load flow in distribution systems has been modelled using a novel technique based on the particular topological traits of radial distribution networks, which has been thoroughly explored to allow for a direct solution. The use of time-consuming decomposition or Bus admittance matrix in standard load flow methods is no longer essential due to the suggested method's direct solution. By comparing the rows and columns of the branch path matrix, this novel approach derives the elements of the impedance matrix. Because it only employs one matrix in its method, the suggested load flow algorithm requires less memory for any size distribution network. As a result, it achieves faster convergence with fewer iterations and is more stable. The suggested method's effectiveness is tested on a variety of standard IEEE test systems for various load models and compared to current techniques. The proposed method's validity is demonstrated by the test results.
