Fukushima Prefecture has a goal of 100% renewable energy use in the primary energy in the fiscal year of 2040. Some renewable powers are unstable and disrupt the grid’s operation.Digital Grid Router(DGR)solves this problem. DGR has been invented by Rikiya Abe, Project Professor of the University of Tokyo. DGR can connect an unlimited number of renewable powers in the cells with DGR, in which AC/DC/AC conversion is performed, to the conventional grid. Its technology contributes to the goal of Fukushima Prefecture.
