We will create an urban operating system of smart cities/compact cities that can improve the efficiency and sophistication of functions and services in cities and regions in the Society 5.0 era, and respond quickly and flexibly to changes in industrial structure such as digital transformation and subscription. In addition, in order to realize the economical introduction of renewable energy in large quantities, the information and communication network and the power network will be converged together, and the power and information networks with scalability and resilience will be optimized in terms of "power supply to ICT systems" and "power rebalancing between DC microgrids using ICT". We will conduct research and development of a scalable and resilient power and information network converged infrastructure.
