A. 2 Department of Biosystems Engineering, UNESP- S?o Paulo State University, Tup?, Brazil Department of Electrical Engineering, UNESP- S?o Paulo State University, Ilha Solteira, Brazil In the evaluation of voltage stability where must trace P-V and Q-V curves for each contingency, static analysis methods are used, as the method of load flow and continuation power flow, it should be efficient and reliable in order to meet the requirements needed for applications in the planning and operation stage in real-time. Geometric parameterization schemes have been proposed by the authors in Part I of this paper. In this part of the paper, the results are presented graphically and in terms of numbers of iterations, showing that the proposed methods obtains all P-V curves of the IEEE-14 and 30 buses systems (loading margin of pre-contingency N-0) and all loading margin post-contingency (N-1 simple contingency and N-2 severe contingency), both with a reduced number of iterations. http://pubs.sciepub.com/wjcse/2/1/5/wjcse-2-1-5.pdf contingency voltage instability continuation power flow maximum loading point parameterization
