Matpower Ill-conditioned systems v1

<p>According to the definition of [1], an ill-conditioned power system can be described as this system which, despite its solution does exists, it is not reachable using the standard Newton-Raphson technique and a flat start. They are ill-conditioned systems building by combining some available cases from Matpower&#39;s database (see file&nbsp;MATPOWER_Ill-conditioned_systems.txt for information). These systems have been used in some papers for validating novel Power-Flow techniques.</p> <p>[1] F.
