中国电动汽车发展及车网互动对新型储能配置的影响

Study on the Influence of Electric Vehicle Development and the Vehicle-Grid Interaction on New Energy Storage Configuration in China

电力系统新型储能发展预期高,但存在与其他灵活调节资源统筹考虑不足的问题。随着电动汽车持续快速发展,未来电动汽车车网互动必将影响新型储能需求,新型储能规划必须与电动汽车发展统筹考虑。通过分析影响电动汽车发展与车网互动调节能力的关键因素,研判中国电动汽车的发展规模,结合电动汽车用能习惯与电力系统调节需求,构建了中国电动汽车灵活性潜力研究模型,并从系统全局优化角度,评估车网互动灵活调节能力,分析了对中国及其7个区域新型储能配置的影响。

With the continuous and rapid development of electric vehicles,the positive interaction between electric vehicles and the power grid in the future will affect the new energy storage configuration of the power system.In view of the insufficient overall planning of the current new energy storage,resulting in high development expectations,this paper proposes that new energy storage and the development of electric vehicles must be considered as a whole,and pay attention to the replacement of vehicle-grid interaction for short-term new energy storage.The key factors affecting the development of electric vehicles and the adjustment ability of the vehicle-grid interaction are analyzed.Based on the development of electric vehicles in China,combined with the energy consumption habits of electric vehicles and the system adjustment demand,the interaction model of the electric vehicles and the system in China is constructed.The flexible adjustment ability of electric vehicles is evaluated,and the impact on the new energy storage configuration in China and its seven regions is analyzed.
