2050年に向けた日本のエネルギー需給検討： 長期の低炭素化に向けたIntegration Studyの比較検討

摘要

Variable renewable energies such as solar power generation (Photovoltaic) and wind power generation have been installed in large quantities in a wide area. For long-term lower carbonization, in order to maintain the supply and demand balance and to operate the electric power system stably and economical ly, not only the improvement of conventional technology such as thermal power generators but also customer side technologies such as power storages, demand response, etc. would play an important role. Integrated analysis and evaluation technologies of the electric power system taking customer side technologies into consideration would become important. Then we investigated the main software related to power supply and demand analysis integrated these technologies as tools for proper planning of future electricity systems, individual models considering the various technologies of customer side, and examples of ut il izat ion of power supply and demand ana lysis. Based on this investigation, this paper presents results of a comparative review among integration studies for long-term lower carbonization and suggestion of actions for the near future.%東日本大震災と原子力事故の後，2014年4月にエネルギ 一基本計画，2015年7月に長期エネルギー需給見通しがそ れぞれ策定され，我が国のエネルギーの議論は再生可能ェ ネルギーを大幅に拡大する新たな段階に入った.また，2015 年12月のC0P21ではパリ協定が採択され，世界各国は温暖 化対策に関する取組を加速している.特に我が国において は，2016年4月に内閣府でエネルギー·環境イノべ一ショ ン戦略（NEST12050)を策定し，研究開発をより重点的-集 中的に進めていくべき技術を特定して，それぞれの克服す べき技術課題を明らかにした.このように，我が国を含め 世界において低炭素化に向けた取組が2050年を目指して 重要視されている.
