Increasing the ratio of electrical power derived from renewable energy sources and thereby helping to control global warming requires designing an energy society powered primarily by renewable energy by designing a system that coordinates the traditional concentrated grids and the newly developing distributed grids to stabilize the supply of electrical power.

Our research involves advancing the development of technologies and systems for using variable renewable energy as baseload power by facilitating coordination between concentrated grid power and distributed grid power. This would help to ensure the stability of the power supply across society. The supply of energy has been stabilized by the inertial force of synchronous generation methods such as thermal, hydroelectric, and nuclear power. Our goal is to maintain the power supply’s stability even when the ratio of these power sources is reduced. To that end, we plan to push the development of related technologies such as inverter controls and load-following nuclear power generation.
