Architecture, components and operation of an experimental hybrid ac/dc smart microgrid

This work presents the overall architecture and main components of an experimental smart microgrid. These are part of a research and development project, which includes aspects such as the design and implementation of power and protection equipments (e.g. power electronics converters and static switches), the development of energy market strategies, regulatory issues, control and dispatch optimization for the distributed energy resources, implementation of high level operation and supervisory algorithms, among others. Details of the proposed hybrid electrical (ac and dc) architecture are presented and each distributed energy resource is described. Experimental results showing the adopted hybrid droop control strategy are presented.
