According to the international standard,IEEE standard 1585-2002,the MVDC voltages range from 1 kV up to 35 kV,and there is also no unified standard for the commonly used voltage. . However, choosing between alternating current (AC) and direct current (DC) microgrids involves evaluating several factors, including efficiency at different voltage levels. AC microgrids are the most prevalent due to the widespread use of AC in national grids. The analysis highlights the superior efficiency of DC distribution systems over AC systems, supported by detailed advantages. The converter configuration features dual inverters that regulate the power distribution to AC loads and grid. . This study proposes a distinct coordination control and power management approach for hybrid residential microgrids (MGs).
