碳排放最小化条件下电动汽车有序充电策略研究

Research on Electric Vehicle Smart Charging Strategy on Carbon Emission Minimization

针对清洁能源和传统能源发电设备的碳排放特性、清洁能源所在位置以及负荷的时空分布特点等因素,参考历史运行数据,建立电动汽车充电与发电设备边际出力增长关系的模型。考虑电动汽车出行特性及其电池充电特性,建立电动汽车无序充电情景下的边际碳排放增长模型。为更多地利用清洁能源,以减少电动汽车充电行为引起的边际碳排放增长,提出碳市场中电动汽车充电与清洁能源,协同的有序充电策略。最后,以碳费用计算模型为基础,提出电动汽车碳排放的评价指标。在算例中,根据提出的评价指标对电动汽车碳排放进行分析。结果表明,与电动汽车无序充电相比,电动汽车与清洁能源协同的有序充电策略可有效地减少边际碳排放增长和碳费用。

At the beginning,this paper built a generator marginal output power incremental model according to the carbon emission characteristics of the clean energy source and traditional generation devices,geographical location of clean energy source,base load distributions and historical operation data.Then,a carbon emission model based on the scenario of out-of-order electric vehicles charging is built by taking the spatial and temporal driving and battery charging characteristics of electric vehicles into account.After that,in order to take more advantages of clean energy by reducing the marginal carbon emission increase from electric vehicle charging,a smart charging strategy between electric vehicles charging and renewable energy in carbon market is proposed in the model.Finally,carbon emission evaluation indexes are proposed in this paper on the basis of carbon cost calculation model.Results in the case studies show that,the proposed smart charging strategy could effectively reduce the carbon emission.
