DC Microgrids: Benefits, Architectures, Perspectives and Challenges

One of the major paradigm shifts that will be predictably observed in energy mix is related to distribution networks. Until now, this type electrical grid was characterized by an AC transmission. However, a new concept emerging, as networks DC transmission are beginning considered promising solution due technological advances. In fact, we now witnessing proliferation equipment associated with renewable sources, storage systems and loads. Thus, such different contexts. way, taking into consideration requirement for fast integration existing network, have started become important. On other hand, importance development these not only fact amount becoming huge. When compared classical systems, more efficient reliable, having any issues regarding reactive power frequency control synchronization. Although much research work has been conducted, several technical aspects yet defined standard. This uncertainty still obstacle faster transition network. There also need focus study order allow technology day-to-day solution. Finally, there many applications which kind microgrid can used, but they addressed. all important challenges tackled. context, paper presents overview possible solutions microgrid, well faced now.
