低圧一括受電住宅における世帯間電力融通を含めた最適システムの設計に関する研究

摘要

現在，温室効果ガスによる地球温暖化現象や化石燃料の 枯渴といった問題が浮き彫りになっている中で，低炭素社 会の構築は非常に重要な課題である.それに向けて省エネ ルギー化が様々な方法で進められる中で，本研究では家庭 におけるエネルギー削減方法について分析する.%Currently collective electricity reception and its trade among houses are promoted as a method of energy saving. Previous researches investigated the possibility of collective reception at high voltage. In this research, we evaluate collective electricity reception at low voltage and its trade among houses with solar cells and fuel cells. In the collective reception at low voltage, power receiving facility for high voltage is not necessary, although the price of electricity is higher. We develop a Mixed Integer Non Linear Program (MINLP) model of the system, introducing the wheel ing rate as a benefit of the aggregator. Then we adopted the concept of Nucleolus in game theory to maximize the minimum benefit of alI the related houses and an aggregator. By doing this, we design a system that distributes profits fairly among houses and the aggregator.
