マイクログリッドにおける直流技術の適用と実証実験事例

抄録

Implementation of Microgrid system is making progress. There are three major reasons for this. The first is the spread of renewable energy as the distributed power source and the graduate FIT. The second is the increase in local production for local consumption represented by regional revitalization. The last is the response to large scale blackouts due to natural disasters that have frequently occurred in recent years, that is, the improvement of power resilience. In addition, the DC system is being re-examined due to its affinity with renewable energy, electric power distribution in geographical vicinity for local production for local consumption, and resilience resistance due to ease of control. The author, for these reasons, describe the application of DC technology in Microgrids and examples of DC Microgrid demonstration experiments.
