Abstract

We present a general framework for the control of a Direct Current (DC) microgrid with star topology (a common DC bus) consisting of renewable sources of energy, loads and storage devices connected via step-up and step-down DC/DC converters. The control objective is guaranteeing voltage stability in the DC microgrid while delivering power to the loads and extracting energy efficiently from renewable sources. To verify grid voltage regulation among a number of devices via current sharing, we use a Lyapunov-based Input-to-State Stability (ISS) analysis. We consider three control scenarios: distributed, partially distributed and decentralized according to the amount of information available to the controllers.
