    The rapid rise in renewable power generation, Energy storage devices, DC electronic loads, and electric vehicles has forced the technical evolvement of the present Microgrid structure from AC to DC. The DC Microgrid (DCMG) can still work with the AC system but with reduced conversion stages, improved reliability, and efficiency. A single AC-DC converter connected to the utility can source the DC bus, supporting multiple DC generation to feed both AC and DC loads. This reduces the grid's burden and makes the generation system environment-friendly. The present work demonstrates the detailed control strategy of one such DCMG with a hardware setup working at 600V DC. The sources considered are Solar Photovoltaic System (SPVS), Permanent Magnet Synchronous Generator (PMSG)-based wind energy conversion system, Battery, and utility grid. The proposed DCMG can maintain stable DC bus voltage under various dynamic conditions by balancing the power on either side of the DC bus. The presence of a grid is considered to maintain stable AC voltage and frequency for AC loads. The control strategy is simulated in MATLAB/Simulink environment and validated through hardware experiments in the WAVECT WCU300 controller. � 1972-2012 IEEE.
