DESCRIPTION:In this talk\, we discuss an energy-based analysis and control
  framework for microgrids. The starting point is an energy function compri
 sing the kinetic energy and terms taking into account the reactive power s
 tored in the lines. We then shape this energy function with the addition o
 f a tunable voltage-dependent term\, and construct Bregman storage functio
 ns satisfying suitable dissipation inequalities. Several microgrids dynami
 cs that have similarities or coincide with the dynamics already considered
  in the literature are captured in this analysis framework. The twist with
  respect to existing results is that our Bregman storage functions allow f
 or a large signal analysis of the coupled microgrid\, and obviate the need
  for simplifying linearization techniques\, and for the restrictive decoup
 ling assumption in which the frequency dynamics is fully separated from th
 e voltage one. Finally\, we will discuss how our analysis scheme extends t
 o differential algebraic models of the microgrid.
