【摘要】：电动汽车的充放电行为会对电网运行的安全性和经济性产生重要影响。文中首先比较和分析3种常用充电模式的特点与适用场合。其次,基于分时电价机制,分析电动汽车换电站的运营与盈利模式,并以此为依据建立换电站的收益函数。然后,基于一定的简化和假设条件,以换电站运营收益最大化为目标函数,兼顾各类运营约束条件,建立换电站最优充放电策略的线性优化模型。最后,以2种电价定价方式验证建立的模型。算例表明,文中提出的优化模型简单有效,所得研究结果可以帮助电动汽车换电站运营方获得最大经济收益,同时也可以为电网管理部门对换电站的管理与调度提供依据。
[Abstract]:The charge-discharge behavior of electric vehicles will have an important impact on the safety and economy of power grid operation.In this paper, the characteristics and application of three common charging modes are compared and analyzed.Secondly, based on the time-sharing pricing mechanism, this paper analyzes the operation and profit model of the electric vehicle power station, and establishes the revenue function of the power exchange station based on the model.Then, based on some simplified and hypothetical conditions, taking the maximization of operating income as the objective function and taking all kinds of operational constraints into account, the linear optimization model of optimal charging and discharging strategy for switching power station is established.Finally, the established model is verified by two pricing methods.The example shows that the proposed optimization model is simple and effective, and the results can help the electric vehicle power station operators to obtain the maximum economic benefits, and can also provide the basis for the management and dispatch of the power exchange power station by the power network management department.
