| Abstract: | In Hong Kong, the energy consumption of buildings and cars has reached 95% of the total energy consumption. In order to protect the environment, the use of renewable energy and electric vehicles has become a development direction. In this paper, a simulation study on the optimal configuration of energy management between an office building equipped with a renewable energy power generation system and an electric shuttle vehicle is conducted to reduce the overall power demand and building operating costs. The simulation shows that the best renewable energy power generation system composed of 1710m2 polycrystalline solar photovoltaic power generation system and two 800kW wind power generators can meet 50% of building energy consumption and 80% of shuttle bus energy consumption. The seven-volume electric shuttle bus configured in the building not only meets the commuting needs of the building, but also makes the entire energy system more stable, while also providing 16.5% of the building's energy consumption. The shuttle bus provides a good buffer between the renewable energy system and building energy consumption's mismatch. 60% of the electricity generated by renewable energy systems is used for grid connection, while offsetting the amount of electricity the building receives from the grid. This makes the office building a zero-energy building. It can also reduce the electricity cost of building operations and the payback period of the entire system (14 years). Finally, it is concluded that the application of renewable energy in office buildings and electric vehicle systems in Hong Kong is promising. |
