我国未来将进入电动汽车规模化应用的时期,但是这也将对电网运行产生巨大影响,因此合理预测电动汽车充电功率需求具有十分重要的意义。本文主要总结了电动汽车大规模充电的充电功率需求特性及其分析模型。首先展望了电动汽车大规模充电的前景及其给电网运行带来的挑战,从而引出了电动汽车大规模充电功率需求分析的重要性;然后从电动汽车本身、充电设施和电能用户三大方面总结电动汽车充电功率需求特性;接下来从不同发展时综述了电动汽车充电功率需求分析模型的研究情况;最后指出了当前研究的不足,并探讨了今后研究的方向。
The future of our country will enter a period of large-scale application of electric vehicles, but this will have a tremendous impact on the operation of the power grid. Therefore, it is of great significance to reasonably predict the demand of charging electric vehicles. This paper summarizes the charging power demand characteristics of large-scale electric vehicle charging and its analysis model. First of all, the prospect of large-scale electric vehicle charging and the challenges it brings to the operation of the power grid are forecasted, which leads to the importance of large-scale electric vehicle charging demand analysis. Then, the paper summarizes the three aspects of electric vehicle itself, charging facilities and electric energy users The demand characteristics of electric vehicle charging power; Secondly, the research situation of electric vehicle charging power demand analysis model is summarized from different development stages; Finally, the insufficiency of current research is pointed out and the future research direction is also discussed.
