Assessing the validity of a propose stability analysis method in a three phase system with constant power load

This paper presents an analysis with nonlinear tools for stability in systems dominated by the interconnection of power electronics and supplied by distributed generation. Systems like renewable and not renewable energy sources can supply power to the micro-grid, and their loads can behave as CPL. Hence, the search of Hopf bifurcation points is used to prevent oscillations and instabilities in the system.
