Does DC
Distribution
Make Sense?
By Rob Cuzner

RECENTLY READ A LETTER TO THE EDITOR IN AN
IEEE publication in which the statement was made
that "dc is already used where it makes sense; the
same goes for ac." Although this is an argument for maintaining
the status quo of how power is distributed, the fact is that the
number of applications in which dc makes sense is increasingly
growing. The growth in dc microgrids and distribution worldwide is a testament to this fact. A universal concurrence of the
articles in this issue of IEEE Electrification Magazine is that a
widespread adoption of dc distribution is impeded mainly by a
lack of standardization, a lack of experience, and most notably
by insufficient solutions to dc distribution-system protection.
In recent years, the most significant technological developments with regard to dc have been in the area of multiterminal
high-voltage dc (HVdc) distribution. ABB [Allmänna Svenska Elektriska Aktiebolaget, Västerås (ASEA), Sweden Brown Boveri,
Zurich, Switzerland] has developed a commercially viable

network. Voltage source converter (VSC)-based interconnections between offshore
wind farms in the North Sea and Germany are already in place
with planned implementations of multiterminal HVdc distribution across Germany, throughout Central Europe, and into
Northern Africa, as well as China. Embedding dc into the ac grid
will result in a more controllable and precise power exchange
and will enable significant mixing of renewable energy with
regional power sources. On a global scale, the potential is for the
reduction of greenhouse gases, increased energy independence,
and improved resilience of electrical power delivery systems.
