Outline of Final Research Achievements

This study started for the purpose of developing an optimizatin method which automatically adjusts the weighting factors among various relating evaluating functions. It gives us a realistic goal which is useful in the coming age of Japanese power grid in which we need to survive the new era of multiple decision makers standards. The proposed method gives us an appropriate schedule via DEA method which controls the relation between various viewpoints among the stakeholders.
However, due to the change in our society, our biggest technical issues have become the newly installed natural energy based power generation such as PV. This study changed its direction to the consideration of these fluctuating power generation and takes into acoount the effects of such intermittancy and probabilistic factors. The final outcome of this study is a proposal of a new method which also considers the uncertainty of the power generation from PV.

Academic Significance and Societal Importance of the Research Achievements

本研究で得られた計算アルゴリズムを用いると，ある程度の不確実性の幅をもって今後の系統運用の形をどのようにすべきかについての一つの解答を得ることができる。これは現在大きな技術的課題となっている昼間の火力発電所の需給運用における下げ代の問題に答えるものであり，これは今後さらに重要性を増していくものと思われる点である。
なお，当初の制度改革に関連する検討の中で得られた複数意思決定主体が関与するケースにおける最適化は，実際の系統における現実的な一つの回答ともなる。
