Power grid stability and security are challenging problems with significant economic and social impacts that have been exacerbated in recent years by the increase in extreme weather events and cyberattack concerns. Recently, networked microgrids (NMs) have become an emerging paradigm that demonstrates resiliency benefit to their local customers. However, lack of awareness of stability margin, inadequate capability to respond to grid disturbances, and vulnerabilities to communication failure, delay, and cyberattacks all contribute to undermine the capability of NMs to improve distribution grid resiliency. To tackle these issues, a set of novel methods are devised in the cyber and physical layers of NMs. Formal Analysis (FA) and Distributed Formal Analysis (DFA) via reachable set computation are established in the physical layer of NMs to efficiently assess their stability in the presence of heterogeneous uncertainties induced by high penetration of distributed energy resources (DERs). Beyond the NM physical layer, a Software-Defined Active Synchronous Detection (SDASD) is designed and implemented in the cyber layer of NMs to protect them from cyberattacks and power bot attacks. The new technologies collectively lead to a set of powerful tools for planning, operating, and protecting future NMs.
