| Abstract: | With the development of the world economy, energy consumption is also increasing. In the past few decades, fossil energy has caused global problems such as climate warming, energy crisis, and natural ecological environmental damage. Therefore, we need to increase the use of renewable energy to reduce our dependence on fossil energy. In all energy consumption sectors, the energy consumption of construction and transportation accounts for a considerable proportion. In Hong Kong, for example, construction accounts for 64% of the total energy consumption, and transportation accounts for 31% of the total energy consumption. In recent years, with the technology maturity of floating photovoltaic panels and offshore wind energy and the growing market share of electric vehicles, their application in a single building is possible. This study uses TRNSYS software to establish a simulation model to simulate renewable energy power generation systems' optimal energy management configuration and the energy storage system between a single building and a vehicle. The results show that when the renewable energy system uses 169m2 floating photovoltaic panels and three offshore micro fans, the annual electricity generated by renewable energy can cover 95% of the annual demand of buildings and vehicles. With the expansion of the scale of renewable energy, when the configuration of renewable energy power generation side reaches 186m2 PV + 3 wind turbines, and the capacity of domestic battery is not more than 54kW, the system can achieve the negative value of annual carbon dioxide emissions, that is, effectively reducing carbon dioxide emissions. In addition, the effects of different configurations of renewable energy systems and different capacities of household batteries on the overall performance of the system are analyzed. |
