纯电动公交车与区域电源结构协同发展的碳排放效益研究

Research on Carbon Emission Benefit of Coordinated Development between Pure Electric Buses and Regional Power Supply Structure

纯电动汽车以其绿色环保而得到了政府的关注与支持,我国电动汽车行业迅速发展,纯电动公交车在城市的占比日益增加,且纳入了各个区域的发展规划。在以火力发电为主的区域,推行电动公交车是将碳排放转移到了发电侧,并不能实现真正意义上的零排放。所以在考虑线损、充放电效率以及负载等因素的基础上,基于相同的出行服务构建了纯电动汽车碳排放计算模型,并以北京市为例计算了合理的适合大力发展纯电动公交车的电源结构,为区域纯电动公交车的发展提供了参考。

Blade Electric Vehicle has get attention and support from the government with its greens environmental protection.With the rapid development of electric vehicle industry in China,the proportion of pure electric buses in cities is increasing rapidly,and it has been incorporated into the development plan of various regions.As we all kown,in the region dominated by thermal power,the implementation of electric buses is the transfer of carbon emissions to the power generation side,and can not achieve the true zero emissions.Therefore,the paper builds a pure electric vehicle carbon emission calculation model based on the same trip service with the consideration of line loss,charge and discharge efficiency and load factors.Then takeg Beijing city as an example,this paper calculate the reasonable power supply structure that is suitable for developing pure electric buses,which provides a reference for the development regional pure electric buses.
