电动汽车（EV）的车到网（V2G）控制等负荷调度被认为是促进风电并网的一种有前途的方式。本文提出了一种基于安全约束单位承诺（SCUC）的电动汽车和风力发电的合作模型。与现有的工作不同，它特别关注电动汽车聚合器的模型和约束。模型中包含了用户出行的分布规律，并分析了储能的动态过程。理论上证明了电动汽车不能同时充放电的限制在某些条件下是多余的，并通过数值例子解释了电池存储限制的必要性。所提出的模型在 IEEE-RTS 的案例研究中得到了验证。结果表明，V2G不仅可以提高火电机组效率，还可以促进风电并网。还分析了影响存储违规的因素。
Load dispatch such as Vehicle-to-Grid (V2G) control of electric vehicles (EVs) is taken as a promising way to promote the integration of wind power. This paper proposes a cooperation model of EVs and wind generation based on the security-constrained unit commitment (SCUC). Different from existing works, it pays special attentions to the model and constraints of EV aggregators. The distribution pattern of user trips is included and the dynamic process of stored energy is analyzed in the model. The constraints that EVs can't charge and discharge simultaneously are proved to be redundant under some conditions on theory and the necessity of battery storage constraints are explained via numerical examples. The proposed model is verified in case studies on the IEEE-RTS. The results show that V2G can not only improve the efficiency of thermal units but also promote the integration of wind power. Factors influencing storage violations are also analyzed.
