Power management for a DC MicroGrid integrating renewables and storages

Abstract : A power management controller for a DC MicroGrid containing renewable energy sources, storage elements and loads is presented. The controller ensures power balance and grid stability even when some devices are not controllable in terms of their power output, and environmental conditions and load vary in time. Power balance and desired voltage level for the DC MicroGrid are considered as constraints for the controller. Simulations and an experimental setup are implemented to show the effectiveness of the proposed control action.
