The aggregation of distributed energy resources (DERs) near the loads to form microgrids was proposed for solving numerous problems faced by the traditional electric power distribution system. To address the growth in microgrid deployment, it is essential to guarantee that these systems are highly robust under all operating conditions, or in other words, they remain stable despite uncertainties. This ability to withstand disturbances and adapt to changing operation scenarios has been identified as a key aspect of the future electric grids. In this dissertation, different scenarios that cause collapse or may lead to instability in a mixed source microgrid are analyzed. Robust control theory is applied to determine the range of stable operation for uncertain parameters. Then, robustness metrics inspired in ecological systems are explored for proposing guidelines to the most robust configurations for a microgrid. Finally, shifting to a non-linear analysis, a controller to aid with coordination of controls is proposed to prevent a cascading collapse when a mixed source microgrid in exposed to a large load change.
