There are different methods to connect DC microgrids to AC grids. In general, the use of a transformer is suggested to increase reliability and isolate the two sides. In the initial structures, it was suggested to use a low-frequency transformer followed by an AC–DC. . HAL is a multi-disciplinary open access archive for the deposit and dissemination of sci-entific research documents, whether they are pub-lished or not. The documents may come from teaching and research institutions in France or abroad, or from public or private research centers. These systems can vary greatly in size and power, from small islands with several motors on a shared DC bus up to large-scale applications, such as entire factories or data centers with combined loads. . Abstract: DC microgrids have emerged as a promising solution in modern power systems due to their simpler structure, lower cost, higher reliability, and superior power quality compared to AC microgrids. Converters are critical components in the operation of DG microgrids as they ensure proper load sharing and harmonized interconnections between different units of DC microgrid.
