1. Work on Implementing Power System that Supports Society 5.0
Proposals are being put forward about the future energy system for Society 5.0. In June 2016, Hitachi established its Hitachi-UTokyo Laboratory as a new scheme for collaborative creation between industry and academia. Against a background in which an unstoppable shift is taking place toward a new system that includes wider use of renewable energy, greater use of distributed energy supplies, digitalization, and electrification, this laboratory is identifying the technical challenges as well as the policy and regulatory issues and developing common understandings of the problem with other stakeholders, while at the same time making this work public*.
Amid rapid changes in the structure of the economy, society, and industry, there is a need for energy systems that suit their local communities, working in harmony with a variety of other infrastructure. Because of the regional variations and fluctuations over time that come with the adoption of renewable energy, it is difficult to limit the management of energy supply and demand and its pricing to single communities. Bulk power systems tie together a number of communities and act to coordinate the system as a whole. The division of roles between bulk power systems and community energy systems is no longer unchanging. Hitachi intends to rebuild those systems on the basis of their coexistence.
