In Japan, there are subjects that surplus power and regulator shortage by introducing a large amount of photovoltaic in recent years. As the results, it is necessary to suppress the output of photovoltaics to maintain supply and demand balance. It has been proposed that output control and utilizing electric vehicle for improvement of these issues. However, these preparations are not enough to solve those issues. In this study, we propose surplus power transaction system by using blockchain and smart contract. In addition, we measured transaction fee and elapsed time in proposed system.
