  • 100% Renewable Energy System in Residential Houses with Photovoltaic and Electric Vehicle

抄録

<p>The purpose of this study is to examine the feasibility of 100 % renewable energy systems in the residential area. The boundary of the residential area was a set of “all-electric houses” that have electric vehicles, photovoltaic and heat pump water heaters. In each case, we derive the power self-sufficiency ratio and power self-consumption ratio by photovoltaic defined by the boundary. Comparing the presence or absence of power interchange, in the case of electricity interchange, the photovoltaic surplus in a home that does not stay the electric vehicle in the daytime can be charged to another home's electric vehicles and used for power supply at night. It was confirmed that the power interchange in residential areas has the effect of increasing the self-sufficiency ratio by up to 14.0 % and the self-consumption ratio of electricity by up to 15.7 % and reducing the annual CO2 emission by up to 18.3 %. In comparison with regional characteristics, in areas where there are many commuting electric vehicles such as the sub-urban area, the electric vehicle does not stay home in the daytime, and the photovoltaic power generation cannot be charged. Therefore, the effect of the photovoltaic - electric vehicles system on the realization of RE100 is small. When there are multiple electric vehicles in one household as in the rural area, it was confirmed that the photovoltaic - electric vehicles system was effective in realizing RE100 by introducing mega solar in the area.</p>
