民生部門を対象とした地域電力需要シナリオの作成: 蓄電池を用いた系統負荷ピークカツト効果の分析

摘要

For pursing a low-carbon society, a variety of new products, such as photovoltaic(PV) systems and electric vehicles(EVs), have been introduced to electricity networks. However, it is unclear how those products will be disseminated in our society and will influence future electricity networks. To explore how future electricity networks might unfold, this paper describes future scenarios of regional electricity demand, focusing on residential and commercial sectors. We develop a simulation model that estimates electricity demand and effects of peak-cut in residential and commercial sectors. The simulation model estimates electricity load including solar power generation and electricity demand to charge EVs, based on diffusion patterns of PV systems and EVs. In the scenario, we analyze effects of peak-cut of electric load utilizing EVs as storage batteries. The simulation results in 2030 show peak of electric load in residential and commercial sectors can be reduced to 72.9-82.5% by the electricity management.%本研究では，これまで開発してきた家庭用次世代電力需要モデルと，新規に開発した業務部門次世代電力需要モデルを組み合わせて用いることにより，民生部門へのPV，EVの普及が電力需要に与える影響と，EVの蓄電池を利用した電力マネジメントによる効果を推計することできた. 大阪府豊中巿を対象としたシナリオでは，家庭•業務部門で一体となって電力マネジメントを行った方が高いピークカツト効果が期待できることがわかった.その一方で，電力マネジメントを行うと蓄電池の充放電によって電力の総消費量は大きくなってしまうことが確認できた.
