The generic solution proposed in this paper aims to provide a universal power conversion mechanism between DC supply and AC/DC microgrids. Typically, power conversion stages may involve isolated high-frequency stages to ensure efficient and stable operation.
Power electronic converters (PEC) connect the DC microgrid to grid utility as depicted in Fig. 1. with several voltage levels and energy storage devices on the DC side that control demand variation, a DC microgrid can deliver power to DC and AC loads . Fig. 1. DC microgrid topology.
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. In DC microgrid, various components are linked in parallel.
In order to overcome this problem, the scheme of grid forming converters (GFMCs) has been presented and the converters' control is done through the characteristics of energy transfer of SGs. In DC microgrids (DCMGs), the SGs equations are inefficient.
tronic converters used in DC microgrid are discussed. Power electronics converters used in DC MGs are grouped and evaluated according to their targets. These power electronic converters
