There has been an increasing global interest in the integration of renewable energy resources (RESs) and energy storage systems into the distribution networks. Moreover, large-scale deployment of electric vehicles and their charging stations has been gaining interest worldwide. Inspired by the “System of Systems (SoS)” concept, we envision the future power distribution systems as “Microgrid of Microgrids (MoM),” which is a group of dedicated microgrids with their own generation, storage, and controllable loads that are capable of operating independently and flexibly reconfigure themselves to create new groups of more complex system(s) that improve system reliability, stability, and efficiency through an adaptive control and self-healing strategies. Such MoM concept has never been proposed or investigated before. This proposal intends to develop a new three-level, hierarchical adaptive control, and self-healing strategies for smart MoM distribution networks to enable flexible-boundaries and coordinated-structure of multiple microgrids to improve the overall distribution system performance.
