| dc.description.abstract | From industrial age to now, greenhouse gas emissions have increased sharply, causing severe air pollution and climate change. Industry and transportation are the main sources of greenhouse gas emissions, therefore, renewable energy and green transportation are receiving more and more international attention. Most countries have turned their energy policies to invest in the development of renewable energy, and major car manufacturers are actively developing electric vehicles, hoping to use renewable energy and green transportation to reduce greenhouse gas emissions. Taiwan is highly dependent on imports of resources, and with the increase of population and economic growth, the use of automobiles is increasing year by year. How the government promotes renewable energy and green transportation has become a key issue. Therefore, this study will focus on electric vehicles, take Taiwan city as the research area, and use mathematical models to carry out the study.
It is difficult to store large amounts of electrical energy, so emergency power supplies are important when power sources are unstable or power is out. The traditional ＂Vehicle to Home＂ (V2H) system is designed to reduce the charging cost by using the electric vehicle battery as a backup load, charging the electric vehicle at cheaper off-peak electricity prices, and discharging it at the peak of the next day. This study uses the concept of using electric vehicle batteries as a backup, build a Stand-Alone V2H system that is not connected to the power grid and combined with renewable energy to generate electricity, all sources of electricity are using renewable. Then collect data on household electricity consumption. Under the scheduled time of households using electric vehicles, when the electric vehicle is not used and parked at home, the electric vehicle battery can be used as an emergency power, and calculated how many solar panels need to be installed to meet the overall electricity demand based on the amount of sunlight in the area, so the amount of sunlight is an important reference for decision makers. The results show that households using Stand-Alone V2H systems can achieve flexible energy management and reduce carbon emissions by about three tons a year. In the future, if large number of households use V2H system combined with renewable energy, it can not only improve energy independence, but also reduce environmental pollution in Taiwan. However, compared with other traditional power generation, renewable energy generation in Taiwan has lower energy density, so it will have higher power generation cost. Therefore, how to balance power generation cost and environmental protection will be a major research topic in the future.
