Computing system parameters to maximize the distance to saddle-node bifurcations

A new methodology to calculate parameters of a nonlinear system to maximize its distance to a saddle-node bifurcation is presented. The technique is thoroughly justified and demonstrated in sample power systems, specifying the conditions when it can be applied and the numerical mechanisms to obtain the desired solutions. A comparison is also carried out between the proposed method and a known methodology to determine closest saddle-node bifurcations in a particular power system model, showing that the new technique is a generalization of the previous method
