This document discusses the design and implementation of a universal DC microgrid. It proposes using an aggregated model of renewable wind and solar power generation to support day-ahead and real-time scheduling. It also develops a droop control for power electronic converters connected to battery storage that adapts droop curves as a function of storage state-of-charge to maintain supply-demand equilibrium in real-time. The microgrid vertically integrates previously untapped wind and solar resources on a high-rise building to support electric vehicles.
