An improved version of the Continuous Newton’s method for efficiently solving the Power-Flow in Ill-conditioned systems

This paper tackles the efficient Power-Flow solution of ill-conditioned cases. In that sense, those methods based on the Continuous Newton’s philosophy look very promising, however, these methodologies still present some issues mainly related with the computational efficiency or the robustness prope...
