要約(日本語): This paper proposed an autonomous DC microgrid system that has many nanogrids in each house connected by DC bus with autonomous dispersion control. The each nanogrid system has a DCDC converter for DC power transmission and a secondary battery, a photovoltanic power generation system. The aim of this system is not only to realize effective autonomy dispersion type electricity distribution system nut also to raise availability of unstable renewable energy such as sunlight energy by the secondary batteries and the intermittent DC power exchange system. The system may flexibly cover from a community size DC micro grid system of bus type to large-scale power distribution system of the scale-free network type because of a simple battery stored energy leveling logic among near systems. We call this system “Open Energy System” (OES) as a next-generation electric power system candidate mainly composed of the renewable energy.
