| dc.title | Interaction between zero energy system which includes metro station, train and a taxi charging station | en_US |
| dcterms.abstract | The development of new energy power generation system technology and the maturity of electric vehicle technology using replaceable batteries provide the possibility for the construction of guarantee new energy power generation system, electric taxi changing station and zero-energy building system of subway station. This paper conducts a simulation study on the optimal configuration and design of the new energy generation system, energy storage system and control strategy of the zero-energy building system, aiming at solving the common problem of the mismatch between the new energy generation system and the power side of the subway station. Under the background of weather conditions in Shenzhen, the paper analyzes the significance of zero energy building system in reducing the carbon dioxide emission of subway station and the simple calculation of the time limit of return on investment. In this study, a zero-energy building system model was established by using the software TRNSYS 18, and the energy control strategy was simulated through the equation module. Through the analysis of the research results, the 8,544 m2 photovoltaic array solar power generation system and the configuration of two 300kw wind turbines can cover 100% of the power demand of the subway station and reduce the annual carbon emissions of the building system by 195,883kg. With the gradual improvement of the configuration of the new energy power generation system, the corresponding amount of replaceable batteries as the energy storage system also needs to be increased accordingly. By increasing the number of replaceable batteries, the mismatch between the new energy power generation side and the power side of the subway station can be reduced by 80%. For the whole system, the term of return on investment is 12-26 years. Although the term of return on investment is much longer than that of small zero-energy building systems, the design life of subway stations and commercial public buildings is limited to the significance of environmental improvement, but far exceeds that of a single family's zero-energy building system. In addition, if new energy support policies are added to help, the return on investment period is expected to be significantly reduced. Therefore, large zero-energy building systems including subway stations, electric vehicle charging stations and commercial buildings have a broad application prospect in Shenzhen. | en_US |
