A Study of Neutral Conductors and Grounding Impacts on the Load-Flow Solutions of Unbalanced Distribution Systems

This paper presents detailed analyses of unbalanced distribution systems with special attention to the multiple load-flow solutions in the presence of neutral conductors and neutral groundings. Some simple distribution systems and some IEEE Test Feeders are used for the identification of the problem...

Description
Summary:This paper presents detailed analyses of unbalanced distribution systems with special attention to the multiple load-flow solutions in the presence of neutral conductors and neutral groundings. Some simple distribution systems and some IEEE Test Feeders are used for the identification of the problems and to perform sensitivity analyses to investigate attraction potentials towards solutions and cases of non-convergence.
