Resilient Networked Microgrids. By Dr. Mehmet Cintuglu and Dmitry Ishchenko. Microgrids enable distributed energy resource (DER) penetration through their ability to provide a convenient interconnection mechanism between the DER providers, facilities and aggregators to be integrated in the national critical energy delivery infrastructure.
Networked microgrids consist of several neighbouring microgrids con-nected in a low/medium distribution network. The primary objective of a network is to share surplus/shortage power with neighbouring microgrids to achieve mutual cost-effective operation, utilising green energy from renewable energy resources in the net-

Networked microgrids have been a significant topic for research.
The configuration of networked microgrids encompasses three key aspects: formation, power distribution, and operation. Formation involves allocating distributed energy resources (DERs) in each microgrid, establishing boundaries, and determining the physical and operational connections between microgrids to shape the overall structure of the networked
