Abstract

Microgrids could be the answer to integrating distributed energy resources into our power grid. It promises improved resilience, reliability, efficiency, and decarbonizing of our electric grid. This paper models a low voltage direct current microgrid using a DAE formulation on a complex network. We then offer a novel method to compute a stability metric using the logarithmic norm which can be used to isolate disturbed nodes.
