Study on the performance of newton – raphson load
flow in distribution systems

Abstract

The reliability of the Newton-Raphson (NR) approach of Load Flow Solution is comparatively better than the other load flow techniques, as unlike other methods it can solve cases that lead to divergence, but the NR method too has some limitations. It has been observed that this method fails under some ill-conditioned situations. The distribution systems usually fall into the category of ill-conditioned power systems. Experience of such failures while applying the NR method in distribution systems encourages investigation of various ways of improving the reliability of the NR approach. Hence, the objective of this project is to study the application of NR method in load flow studies and determine the various difficulties faced while using the method for physically feasible problems, particularly in distribution systems.
