Block-level microgrids for power system resilience: Scaling and impacts

Abstract

This paper presents a new approach for the coordination and scaling of microgrids, known as EcoBlocks, and discusses the ability of EcoBlocks to function as electrical islands in an adaptive manner. We analyse the impacts of EcoBlock design elements such as block size, energy management strategies, and DC power distribution on grid resilience, flexibility and efficiency under large-scale deployment. By enabling new operating schemes including routine grid support as well as adaptive islanding during major disturbance events, EcoBlocks could significantly enhance the beneficial role of microgrids for grid resilience.
