AC MicrogridsDC MicrogridsWhy Choose Microgrids?Choosing The Right MicrogridThe operational principle of DC microgrids is quite similar to their AC counterparts. The main difference between them is the DC bus network for interconnection rather than the AC bus which interconnects the distributed generators and loads in the network. The operational voltage of these DC buses often ranges from 350 to 400 Volts. The main DC bus...See more on veckta Wikipedia

Architectures are needed to manage the flow of energy from different types of sources into the electrical grid. Thus, the microgrid can be classified into three topologies: Power sources with AC output are interfaced to AC bus through AC/AC converter which will transform the AC variable frequency and voltage to AC waveform with another frequency at another voltage. Whilst power sources with DC output use DC/AC converters for the connection to the AC bus.
