Connecting human beings and things is crucial for the "Society 5.0," where electricity is stored and supplied to devices in most of their applications. Electricity generated from renewable energy is also stored before its usage in most cases. The technologies to store and use electricity in smart ways are inevitable for sustainable economic growth. We propose the virtual grid for supplying devices with stored electricity without restriction of fixed power grids. There are 1.1 billion people living without electricity, and some of them have started using small solar energy systems with batteries. We expect to apply the virtual grid to their systems, and eventually contribute to increasing renewable energy usage in the world. In the demonstration, electricity stored in the batteries with different capabilities of output power and storage capacity is provided to devices connected by the virtual grid hub under the user-defined power provisioning policy.
