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.
Additional components in a DC microgrid besides the AC/DC grid connection, renewables, battery systems and various loads include circuit breakers, precharge units, monitoring systems and auxiliary supplies for attached systems. Figure 1-1 shows a DC microgrid and possible system blocks. Figure 1-1. Components and Loads in a DC Microgrid
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.
