摘要
电动汽车不仅为减少CO2排放量提供了独特契机,而且对于电力系统而言还具有平衡能力和提供备用服务的功能。结合丹麦电力系统及社会的特点,通过成本效益分析,阐明了具有智能充/放电功能的电动汽车在保证含有大规模可再生能源的电力系统可靠运行方面具有很大的潜力并会带来显著经济效益。通过分析,明确了目前在电动汽车应用方面存在的重要技术问题,阐述了为设计含大规模风电和电动汽车的丹麦电力系统而建立的EDISON项目的相关研究和开发方案。介绍了EDISON项目的最新进展,即采用虚拟发电厂技术实现电动汽车智能充放电的管理。
Electric vehicles（EVs） provide a unique opportunity for reducing the CO2 emissions from the transport sector.At the same time,EVs have the potential to play an important role in the economical and reliable operation of an electricity system with high penetration of renewable energy.An analysis is made of the potential for using EVs in Denmark,and the benefits of the electric power system with high wind power generation by intelligent charging and discharging of EVs are enumerated.Based on the analysis,important technological gaps are identified,and the corresponding research and development initiatives of the recently established EDISON program are described.Moreover,the latest development of the EDISON program is treated,that is,EDISON as a research consortium to design a new model for the Danish power system with high penetration of wind power and EVs with vehicle to grid（V2G）.The managing structure of V2G adopting virtual power plant（VPP） technology is proposed.
