Abstract

我が国ではCO<sub>2</sub>排出量の削減だけでなく輸入エネルギーを国全体として削減することが喫緊の課題となっている.そのためには,自然エネルギーと省エネルギーを組み合せた経済性のあるエネルギーシステムの構築と拡大が重要になる.そのひとつに,太陽光発電(以下,PVと記す)と電気自動車(以下,EVと記す)を組み合せたスマートPV&EVシステムが提案されている.本論文では,PVの電力をEVへ直接充電し,家庭などへ供給するシステムの効率と経済性について検討した.その結果,提案するシステムは,PV電力を系統経由で供給するメガソーラなどと比較して,発電したPV電力を10%以上有効に利用できるとともに,電力固定価格買い取り制度などの仕組みがなくてもIRR=5.5%の経済性を有することを明らかにした.

Japan has urgent issues which are not only reducing CO<sub>2</sub> emissions but also reducing imported energy as the whole country. To accomplish this, it is important to construct and expand an energy system that can be combined with natural energy and energy conservation. The system should also satisfy economic efficiency for the end consumer. In one of the solutions, “the Smart Photovoltaic power generation (hereinafter referred to as PV) & Electric Vehicle (hereinafter referred to as EV) System” has been proposed. This system combines both the PV and EV. In this paper, a novel system which is direct charging with PV power to EV and then supplying that power to a home has been studied. As a result, it is clarified that the proposed system can utilize PV power more efficiently than mega-solar through the use of power system. Additionally, it is IRR=5.5% of the system without the Feed-in Tariff scheme and various subsidies. IRR of the new system is higher than IRR of Feed-in Tariff scheme.
