The concept of “Digital Grid” has been developed at department of Technology Management for Innovation, Graduate School of Engineering, the University of Tokyo. The Digital Grid solution is to segment the grid into substantially self-sustaining regions or “cells,” then control the flow of energy between those cells using controlled and scheduled energy flows. A Digital Grid Router (DGR) is a computer-controlled multi-leg AC/DC/AC converter with internet communications. A Digital Grid Controller (DGC) makes energy transfer requests, initiates and terminates energy transfers, implements the energy transfer protocol, and provides autonomous operations for each active element in a cell. Each DGR and DGC are assigned unique IP addresses and communicate using an IP protocol like on the Internet. Blockchain research done by Dr. Kenji Tanaka, Associate Professor at department of Technology Management for Innovation, is used in the Digital Grid power trading system on the cloud server accessed from DGCs.
The DGR transmits power and information together. The power identifications such as power trading information, source origin and destination, and other important data are encoded in the information. This feature proves the original power source and brings us to accelerate installing more renewable energy for reduction of CO2.
