Measured Advantages of a Production Plant with DC Grid in terms of Energy Efficiency, Peak Power Reduction and Power Quality

Due to the increasingly widespread use of efficient power electronics, DC grids today offer more and more advantages over AC grids. Based on comparative measurements, this paper shows that an efficiency increase through DC can be achieved even with little recuperation potential of an existing system. In addition, other advantages such as peak load reduction by -43 %, power quality improvement and reliability are documented.
