Digital Grid (eBook)

This book is about Digital Grids, which eliminate the electrical constraints of power grids, provide a mechanism for free electricity trading, make full use of renewable energy, and remove human energy constraints.

It is rare to experience an era of great change that shakes the social structure. The great transformation of the social structure brought about by the Internet is just one of them. It is doubtful that people at the time when that transformation began could realize just how great and momentous the change would be, but now all indications are that the energy industry will bring about a major transformation of the social structure. This book, The Digital Grid, aims to show the far-reaching effects of that concept and how it will be realized.

Rikiya Abe (Ph.D.) is the CEO of DG Capital Group Corporation. The company, along with its subsidiaries, produces grid-forming inverters (DGR) using digital grid technology and operates AC main grid with grid forming that supplies synchronizing force and inertia.  DGR also provides primarily renewable energy sources with a duplicated DC sub-grid redundant to the AC grid. They also design small wind turbines and DC generators. These were established to incorporate renewable energy sources into power systems with many constraints. Dr. Abe also serves as the representative director of the non-profit Digital Grid Consortium, which promotes digital grids through educational activities and consulting. With years of experience as an electrical engineer at J-POWER, a Japanese wholesale electricity company, Dr. Abe dedicated his research and development efforts to the concept of digital grids as a specially appointed professor under the direct control of the president of the University of Tokyo since 2008. In 2012, he founded WASSHA, which provides renewable energy in un-electrified areas. Furthermore, he established the Digital Grid Company in 2017, constructing a private market for energy and environmental values in Japan, facilitating transactions between many power generators and consumers.
