The Second ICDCM will be held in Germany, a hotbed of dc power technology, following on the heels of a successful first conference in Atlanta, GA, USA in 2015. The conference aims to bring together practitioners and researchers in the field of dc microgrids and related technologies to advance our understanding and capability for endpoint use of dc power. Technical sessions will be arranged around two foci – use of dc at the commercial and industrial scale, MW, and use at the residential scale, kW. DC power promises easier integration of variable speed machinery and renewable or co-generation power sources, simpler connection of energy storage, and higher power reliability. Use of locally-generated dc power will reduce dependence on long-distance transmission and distribution networks, reduce grid congestion, and will transform the electricity infrastructure. The benefits of dc microgrids powered by renewable resources such as solar PV systems can be especially dramatic in those parts of the world that don’t already have power infrastructure.
