Various organizations are making efforts to reduce CO2 emissions toward a decarbonized society. Among them, for railway operators, effective utilization of regenerative power is one of the measures to reduce CO2 in the traction power supply system. However, because the equipment for effective utilization of regenerative power is expensive, there is a problem that it can be installed only in places where the effect is high. Therefore, in this research, we focused on highly versatile EV storage batteries and decided to utilize EVs in the traction power supply system. We proposed a framework that benefits not only railway operators but also EV owners by offering a certain amount of free charging to EV owners at stations, which benefits all stakeholders. In addition to setting detailed charging and discharging conditions for EVs, we conducted studies based on annual simulations using actual data. As a result, we were able to gain a detailed understanding of the EV charge/discharge schedule, as well as the extent to which the amount of free charging required to ensure business continuity.
