The Microgrid (MG) concept as an important block of future smart grids provides a quite appealing solution for integrating renewable energy sources (RESs) into the power grids. The increasing interest in penetration of RESs among the MGs highlights the importance of these systems and addresses serious dynamic and control challenges in MGs design and operation. In response to the existing challenges and for integration of advanced computation and control into appropriate levels of MG control synthesis, this speech summarizes academic/research outcomes and contributions of the speaker, that are influenced by the practical experiences in several countries, universities and power electric companies. The speech describes some important issues on MG dynamics and control as well as new relevant perspectives and research outcomes. It addresses some important parts of a new book (in press by Wiley-IEEE) in the relevant area.
