The ideas of rethinking how w e model\, simulate and control complex electric energy systems\, with emph asis on formalizing the role \;of control and computing for supporting resilient\, reliable\, and cost-efficient decarbonization\, are \;cur rently also being taught in an MIT EECS course (6.1720/6.1721). Fundamenta l problems due to \;slow\, inaccurate sensing when tuning controllers against static grid equivalents are illustrated using \;basic circuits . \;In this talk we first review the motivation for this new modeling. Unique features of energy dynamics \;models derived from the first pr inciples are reviewed\, their distributed structure which lends itself to& nbsp\;cooperative interactive multi-layered control and computing. The str ucture supports zoomingin/zooming out modeling into different system layer s and it does not require static equivalencing. The structure\, when explo ited\, makes it possible to model interaction dynamics between often \ ; highly heterogeneous multi-energy components equipped with controllers d esigned by different manufacturers (notably\, control induced system stabi lity (CISS) already experienced in systems with \;large penetration of renewables). \;We illustrate on microgrids the potential of nonlinear control design using energy dynamics\, with \;emphasis on reactive po wer modeling and control. We then pose the problem of end-to-end \;mod eling and control design problems using energy dynamics. We describe how h igher-level \;modeling/control and computing can be posed for provable performance. For this to be done\, it is \;necessary to design next g eneration primary controllers which have provable performance for \;ra nges of energy\, power and rate of change of reactive power. Otherwise\, m any fast dynamical \;problems caused by intermittent power fluctuation s\, large sudden power inputs and topological \;changes (wind gusts\, solar irradiance disturbances\, in rush oscillations created by large indu ction \;motors/wind power plants connection/disconnection\, faults) wi ll remain roadblocks to more \;efficient flexible utilization of avail able resources\, and the grid ability to support decarbonization. \;Fi nally\, we identify in hindsight assumptions currently made when studying and attempting to \;control frequency and voltage during difficult dyn amic conditions. We show that energy dynamics \;modeling simply repres ents an outgrowth of today’s Automatic Generation Control (AGC) and  \;Automatic Voltage Control (AVC) when linearization\, time scale separati on and P-Q decoupling \;assumptions are relaxed. We suggest that stand ardized information exchange becomes possible \;for provable performan ce of future SCADA in support of otherwise highly complex Dynamic \;Mo nitoring and Decision Systems (DyMonDS). \;Reference: [1] M.
