电动汽车与清洁能源融合发展技术研究与展望

A state-of-the-art review on the integrated development technology of electric vehicles and clean energy

以光电、风电为代表的清洁能源发电技术可为电动汽车提供清洁的电力供给,减少全生命周期碳排放,助力交通领域“双碳”战略目标的实现,因此近年来得到迅猛发展。为了推动交能融合技术的应用,明确相关研究中的关键问题,该文综述了国内外学者过去10年在电动汽车与清洁能源融合技术方面的研究进展。首先,介绍了二者融合发展的必要性与现实意义;其次,将已有研究成果分为公路环境与城市道路环境两类,分别从电网、充电站、车辆3个层面归纳了当前电动汽车与清洁能源融合技术的研究成果;最后,考虑到清洁能源发电以及电动汽车充电存在较强的随机波动,对未来发展提出了加强公共领域交能融合发展、构建多种互补型清洁能源发电策略、建立“源—网—荷—储”集成优化技术、强化分布式微电网能源自洽调度、加强无线光伏充电公路运营管理等建议。

The clean energy power generation technology represented by photoelectric and wind power can provide clean power supply for electric vehicles,reduce the carbon emissions of the whole life cycle,and help the realization of the“dual carbon”strategic goal in the field of transportation,so it has been rapidly developed in recent years.In order to promote the application of transportation and energy integration technology and clarify the key issues in related research,this paper reviews the research progress of domestic and foreign scholars in the integration technology of electric vehicles and clean energy in the past 10 years.Firstly,the necessity and practical significance of the integrated development of the two are introduced.Secondly,the existing research results are divided into two categories:highway environment and urban road environment,and the current research results of electric vehicle and clean energy integration technology are summarized from the three levels of power grid,charging station and vehicle.And finally,considering the strong random fluctuations in clean energy power generation and electric vehicle charging,Some suggestions on the future development direction are put forward,such as strengthening the integrated development of public energy,constructing a variety of complementary clean energy generation strategies,establishing the integrated optimization technology of“source-network-charge-storage”,strengthening the self-consistent energy scheduling of distributed micro-grid,and strengthening the operation and management of wireless photovoltaic charging roads.
