AC vs. DC Power Distribution for Data Centers

DC power distribution has been proposed as an alternative to AC power distribution in data centers, but misinformation and conflicting claims have confused the discussion. A detailed analysis and model show that many of the benefits commonly stated for DC distribution are unfounded or exaggerated. This paper explains why high efficiency AC will likely emerge as the dominant choice for data cent...

A New Power Management Approach for PV-Wind-Fuel Cell Hybrid System in Hybrid AC-DC Microgrid Configuration

The hybrid AC-DC microgrid (HMG) architecture has the merits of both DC and AC coupled structures. Microgrids are subject to intermittence when the renewable sources are used. In the HMG, since power fluctuations occur on both subgrids due to varying load and unpredictable power generation from renewable sources, proper voltage and frequency regulation is the critical issue. This article propos...

Transmission and Distribution Networks: AC versus DC

The fast development of power electronics based on new and powerful semiconductor devices has led to innovative technologies, such as HVDC, which can be applied to transmission and distribution systems. The distribution voltage level is smaller than the transmission one, thus the power electronics are less expensive in distribution. The technical and economical benefits of this technology repre...
