Harnessing the Power of DC Microgrids for Industrial
DC microgrids centralize AC-to-DC rectification, resulting in a reduced number of power-conversion stages and a shared DC bus. Centralization reduces conversion losses and improves
DC microgrids are localized energy systems operating from a DC bus within a defined voltage range. 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 reaching up to the megawatts.
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.
Connecting the DC microgrid to the AC grid requires a bidirectional power supply. This supply handles AC-to-DC conversion with a high power factor and must be able to perform DC-to-AC conversion as an inverter. Because of the power levels, efficiency as well as thermal management are of top concern.
Usually, a PV based microgrid system includes solar panels, intermediate power electronic converters with appropriate controllers and the grid/load. A boost derived DC–DC converter is normally employed to step up the low voltage DC output obtained from the PV panels to the desired voltage level [ 4 - 6 ].
