This paper is a generalization and extension of earlier research in parametric optimal power
flow. Its principal features are:(i) the use of a full nonlinear OPF model,(ii) a more general
parameterization of equalities, inequalities and objective function, and (iii) an algorithm that
exactly tracks the OPF behaviour in terms of the continuation parameter. The
parameterization allows one to distinguish between two phases. One serves to find the OPF
solution to a static problem for a fixed load and network starting from an arbitrary initial …
