Smart Micro Grid Energy Management System

a microgrid based on direct current (DC) was designed and simulated. The microgrid’s energy will originate from DC sources, and the island’s loads will be DC as well. As a result, it was suggested that a microgrid based on DC be designed to reduce the amount of conversion losses between AC and DC. Due to the absence of the skin effect, a microgrid based on DC will have minimal power factor losses, fewer corona discharges, and will be a cheaper and simpler system DC microgrids are already used in data centres, aeroplanes, submarines, and other remote sites in the telecoms industry. The individual components of the microgrid were designed and simulated using MATLAB/Simulink. The island’s solar and wind resources, as well as the island’s expected load profiles, were modelled. A financial evaluation was carried out. An AC microgrid with diesel-only generation, which is currently in use, had the highest overall costs, while an AC-DC hybrid microgrid was cheaper than the diesel-only system, and a DC microgrid had the lowest overall costs. A technical evaluation of the DC microgrid was carried out
