The complexity of electronic infrastructure in DC micro grid and possibility of reduce them

Micro-grid is one of new conceptual power systems for smooth installation of many distributed generations (DGs). While most of the micro-grids adopt ac distribution as well as conventional power systems, dc micro-grids are proposed and researched for the good connection with dc output type sources such as photovoltaics (PV), fuel cell, and secondary battery. In this paper, the electronic infrastructure of micro-grid is expressed. Then discussed the reasons for its complexity and the possibility of reducing the elements of electronic circuits are investigated. The reason for this is in order to compact dc micro-grid system for electrification to places like villages.
