With the rapid development of power electronics technology and its successful application, many demonstration projects medium/low-voltage DC (M-LVDC) distribution systems have been constructed. The transformer (DCT) is key equipment in M-LVDC system for interconnecting MVDC LVDC buses. In this paper, characteristics DCTs are summarized. existing topologies analyzed, relevant control strategies ...

General systems theory (GST) holds the potential to address some of the issues that information systems (IS) field faces today. This paper addresses the question whether the concepts, principles and approaches prevalent in GST can be gainfully employed for studying and conducting research in IS. Using the concepts embedded in GST, we analyze the problem of “fragmented adhocracy” in IS research....

Distribution of distributed generation resources in distribution systems has several advantages, including reducing losses, improving voltage profiles, reducing pollution, and increasing system reliability. However, one of the most important points regarding the placement of these resources in distribution networks is economic issues and the return on investment and the increase in profits from...
