A microgrid based on direct current (DC) was designed and simulated for a small island in Belize. The energy generated in the microgrid will come from DC sources and the loads on the island will also be DC. Therefore, it was proposed to design a microgrid based on DC to reduce the amount of conversion losses between AC-DC.
