基于B2G模式下电动汽车参与电网互动运行策略

V2G（vehicle to grid）是目前电动汽车参与电网互动的主要模式，但也存在很多问题，影响电动汽车进一步发展。相较之下，B2G（battery to grid）模式解决了V2G模式下模型庞大繁复，难以控制的问题。提出了一种基于B2G模式下的电动汽车参与电网互动策略，以申报用电调整计划的方式，根据电站实时运行状态，以电站运行经济效益最大化为目标，求解最优用电调整计划，从而达到互动效果。通过银川某电站的示范运行，证明该策略具有可操作性，可以带来良好的经济效益。

Operation Strategy of Electric Vehicles for Interacting with the Grid in Battery to Grid Mode

Nowadays V2G had been employed in large scale as the major way the electric car connect with the grid. However， there had been so many problems that in the V2G mode， such as the huge complex connection calculation models， difficulties in controlling， etc. This should be a huge problem on the way of electric car employed in a bigger scale. Compared with V2G， the mode of B2G could help to solve the questions mentioned above. And in this paper， a novel strategy of electric vehicles in B2G operation mode has been discussed. Taking the real-time operating condition into account， the strategy would provide an optimized solution of regulated power plan for charging stations， which run the economic maximization as the goal. A declaration of regulated power plan would be employed in the strategy mentioned above， which make the vehicles and the grid interact actively. The result of demonstration in some certain charging station in Yinchuan has proved that the strategy is effective and beneficial.
