Outline of Final Research Achievements

This research project aims to reduce the impact of long-term power outages at dialysis clinics due to disasters. Since approximately 40,000 dialysis patient deaths are reported at dialysis clinics per year, the social significance is very large. In this research, the emergency generators at dialysis clinics are treated as virtual power plants. A method was developed to make the power plants compatible with the demand response required by power companies. As a result, the effectiveness of a sustainable power system operation method that takes disasters into account and can respond to early recovery was demonstrated in simulation.

Academic Significance and Societal Importance of the Research Achievements

本研究課題で開発した持続可能な電力システムは、非常時の早期復旧と平常時の経済運用の両立を実現させる運用手法である。日本透析医学会による2018年の統計調査の対象となった約4,500の人工析施設だけでも、その総電力需要は30万kWから50万kWもあり、火力発電所１機分に相当するため、研究成果の社会実装への展開が大きく期待できる。
