Adaptive Islanding and Self-Sufficiency of Block-Scale Microgrids

Abstract

This paper discusses adaptive islanding via city-block-scale microgrids as a new paradigm in electric grid operations, which has the potential to vastly improve flexibility and resilience of the grid and facilitate renewable energy integration. We summarize advantages and challenges of adaptive islanding in general and the block scale in particular. We also present an approach to analyze microgrid self-sufficiency probabilistically using time-series simulations, and demonstrate the benefits of the block scale in an example with real household electric data.
