The microgrid (MG) concept provides a quite appealing solution for integrating distributed generators (DGs) and renewable energy sources (RESs) into power grids. The increasing interest in penetrating renewable energy power into the power system among the MGs highlights the importance of these systems and addresses serious stability and control challenges in MGs design and operation. The MG is known as the building block of modern power grids (smart grids), therefore, MG control is becoming more significant today due to the changing structure, high penetration of RESs and DGs, environmental constraints, and increasing uncertainties of power grids. This speech describes the most important challenges in MG control as well as new relevant perspectives and research outcomes. It covers various levels of MG control including local/primary control, secondary control, central/tertiary control, and global controls. Furthermore, new outcomes and advances in the MGs as network control systems and cyber-physical systems will also be discussed.
