Abstract
DC Microgrids are very popular these days because they can provide qualitative and quantitative energy to remote regions. There is stochastic behaviour and uncertainty in DC microgrids (MG) that use renewable resources. As a result, battery units are required in DC microgrids to assure power balance. Effective coordination and control are necessary for standalone DC MG to accomplish efficient energy management and effective utilization of resources and storage units. A 48V standalone DC MG for remote residences is proposed, consisting of a photovoltaic (PV) system, MPPT, DC/DC boost converters, and storage batteries. Only a few of the challenges include the integration of distributed energy resources (DERs) into DC MG, MPPT, battery charge-discharge control, and voltage deviation control at the DC bus. All of these issues have been considered and investigated in this paper. As a result, the existence of a complete control platform is highly desirable. The entire system is created and tested in the Typhoon Hil environment.
