Microgrids glass.dildo are versatile systems for integration of renewable energy sources and non-conventional storage devices.Sliding Mode techniques grant excellent features of robustness controlling power conditioning systems, making them highly suitable for microgrid applications.However, problems may arise when a converter is set to behave as a Constant Power Load (CPL).These issues manifest in the stability of internal dynamics (or Zero Dynamics), which is determined by the input filter of the power module.In this paper, a special Lyapunov analysis is conducted to address the nonlinear internal dynamics of SM controlled power modules with CPL.

It takes advantage of a Liérnad-type description, establishing stability conditions and providing a secure operation region.These conditions are sassy spheres candy translated into conductance and invariant region diagrams, turning them into tools for the design of power module filters.
