Cover Story: When the grid is unavailable, but renewable energy resources and storage capacity are available, islanded microgrids can be a substitute for the grid to provide renewable energy to loads. This paper presents the design and operation of an islanded microgrid to provide renewable energy to different loads. The microgrid is based on equipment that manages the microgrid via voltage and frequency variations based on the VDE-AR-N-4105 standard. This allows open access to the microgrid, and any equipment that fulfils this standard can be connected as well as managed to allow the proper operation of the microgrid. The paper also addresses protection functions in cases of overloads or short circuits, implementing software tools to prevent the failure of the complete microgrid in the case of a fault. The paper shows a live demonstration of the proposed methods. View this paper
