Abstract

In the future, the number of electric vehicles will increase significantly, promoting the integration of renewable energy into buildings and electric vehicles, which helps to achieve energy greening in transportation and architectural fields. The system includes renewable energy, buildings, electric vehicles, and energy storage systems. In this paper, the mathematical model of each system is established, and the electricity consumption of the building and the power generation of PV panels are predicted by the Energyplus software, and the economic evaluation index is proposed. In addition, the research analyses the effect of electric vehicles as electrical vectors in integrated PV panels and storage. The small solar residential data shows that through building-to-vehicle and vehicle-to-building solutions, on-site renewable energy utilization can be achieved, which is also conducive to building a zero-energyconsumption home.
