摘　　要：中国风电主要从输电网接入,为实现电动汽车清洁充电,有必要从输网侧开展计及碳排放的"风–车协调"研究。根据电动汽车输电网侧调度特点,提出了电动汽车集群调度模型。结合碳捕集和常规电厂电碳模型,建立了综合考虑发电成本、碳排放成本的输网侧"风–车协调"调度模型。在Matlab环境下通过cplex软件对模型进行求解。以IEEE 14母线系统为例,研究了单向有序、双向有序充电下的"风–车协调"在减少全网碳排放和弃风量,平抑火电波动的效果。研究了不同断面约束下"风–车协调"的效果。结果表明,当电动汽车大量接入时,通过有序充电下的"风–车协调",可在不同断面约束下实现汽车清洁充电并提高风电利用率。Because wind energy resources are mainly integrated in transmission grid in China, it＇s necessary to study wind-electric vehicle （EV） complementation on transmission grid side considering carbon emission for clean charging. The EVs＇ aggregated model in transmission grid was proposed according to their characteristic in the transmission grid dispatch. With the carbon emission models of the conventional and carbon capture power plants, the wind-EV complementation model in transmission grid was established wherein both fuel costs and the penalty for emission were considered. The model was solved with CPLEX software in Matlab. The effects of coordination on reducing emission and abandoned wind energy, and leveling power plant output under unidirectional and bidirectional coordinated charging modes, were studied in IEEE 14-bus system. The effects under different transfer capacity constraints were researched. It is concluded that with EVs＇ connected in large amount, wind-EV complementation contributes to realizing clean charge and improving wind energy utilization.
