为了将大规模的可再生能源整合到电网中，电池储能对于平滑其自然不稳定性和确保电网范围的频率稳定性起着重要作用。电动汽车不仅有很大的引进潜力，而且有很长的控制时间，因为它们几乎是作为分布式电池能量存储插入家庭插座的。因此，车辆到电网（V2G）有望成为智能电网战略的关键技术之一。提出了一种自主分布式V2G控制方案。并网电动汽车根据插入式终端处的频率偏差提供分布式旋转备用，该频率偏差是电网中供需不平衡的信号。作为EV利用的一种方式，假设车辆使用者预先设置下一次拔出定时。在这样的假设中，通过对插件执行预定充电来满足用户便利性，并且插件空闲时间可用于V2G控制。因此，在所提出的方案中考虑了智能充电控制。利用典型的两区域互联电网模型和汽车锂离子电池模型，通过仿真评估了车辆用户的方便性满意度和对负荷频率控制的影响。
To integrate large scale renewable energy sources in the power grid, the battery energy storage performs an important role for smoothing their natural intermittency and ensuring grid-wide frequency stability. Electric vehicles have not only large introduction potential but also much available time for control because they are almost plugged in the home outlets as distributed battery energy storages. Therefore, vehicle-to-grid (V2G) is expected to be one of the key technologies in smart grid strategies. This paper proposes an autonomous distributed V2G control scheme. A grid-connected electric vehicle supplies a distributed spinning reserve according to the frequency deviation at the plug-in terminal, which is a signal of supply and demand imbalance in the power grid. As a style of EV utilization, it is assumed that vehicle use set next plug-out timing in advance. In such assumption, user convenience is satisfied by performing a scheduled charging for the plug-out, and plug-in idle time is available for the V2G control. Therefore a smart charging control is considered in the proposed scheme. Satisfaction of vehicle user convenience and effect to the load frequency control is evaluated through a simulation by using a typical two area interconnected power grid model and an automotive lithium-ion battery model.
