As a measure to make renewable energy the main source of electricity for carbon neutrality and to reduce the risk of a balance of expenditure when fuel costs rise, it is necessary to have a mechanism to adjust demand in the residential sector, which accounts for about one-third of all electricity demand. TEPCO and ITOCHU conducted a large-scale verification experiment to confirm the ability of DR commands to control equipment and adjust demand by requesting approximately 300 households to conserve electricity and by controlling equipment through external control of storage batteries. The DR effect was 0.02 kWh per 30-minute period per house in both summer and winter for the behavior-changing DR, and 0.10 kWh in summer and 0.22 kWh in winter for the equipment control type DR. This indicates that DR using storage batteries has a greater effect on demand reduction than DR using the behavior change type, and that it can be done reliably. In the future, we will study and demonstrate the operation method of storage battery control to improve the balance of payments through DR.
