Inverter-Dominated Networked Microgrids with Marine Energy Resources and Energy Storage Systems for Coastal Community Resiliency Enhancement

Distribution grid resiliency enhancement is urgently needed in coastal communities, given the severe power outages induced by natural disasters, such as hurricanes, floods, among others. In this paper, a holistic coastal community resiliency enhancement framework is implemented through multiple networked microgrids (MGs) surrounding marine energy resources (MERs) and energy storage units (ESUs) with minimum capacity requirements. Particularly, the real-time sectionalization scheme of coastal communities is determined online driven by an optimization algorithm to maximize the load restoration during and after severe power outages, and more importantly, to ensure operational continuity in coastal communities, the distributed and resilient control schemes are developed at the MER asset level in coordination with system-level reconfiguration plans to enable autonomous and networked MGs. Further, based on the proposed networked MGs control schemes, system stability is evaluated considering various operation modes. Finally, the effectiveness of the proposed framework is validated using a 13-bus coastal community distribution feeder test system.
