电动汽车考虑部件寿命的实时动态最优功率流

Real-Time Dynamic Optimal Power Flow in Electric Vehicles Considering the Lifetime of the Components in the E-Powertrain

摘要:

不同类型的能源(例如,电池、超级电容器、燃料电池)可用于电动车辆中以通过电力电子装置在电动动力系统中存储和提供能量[1-6]。电动动力系统中部件的寿命取决于其负载曲线[7,8]。例如,电池的寿命在很大程度上取决于放电深度和充电/放电循环次数[9-13]。逆变器的寿命主要取决于通过逆变器的有功-无功功率的变化,这意味着通过在最佳时刻将总功率的最佳份额分配给每个能源和电力电子器件,可以降低部件的寿命消耗成本。此外,通过减少能量损失,即,在其高效率区域中操作部件。因此,有必要在电动动力系统的运行中执行最优功率流(OPF)。

英文摘要:

Different types of energy sources (e.g., batteries, supercapacitors, fuel cells) can be utilized in electric vehicles to store and provide energy in the e-powertrain through power electronic devices [1-6]. The lifetime of the components in the e-powertrain depends on their load profile [7,8]. For instance, the lifetime of a battery highly depends on the depth of discharge and the number of charge/discharge cycles [9-13]. The lifetime of an inverter mostly depends on the variations in the active-reactive power passing through it. This means that the expended life cost of the components can be decreased by allocating an optimal share of the total power to each energy source and power electronic device at an optimal time instance. In addition, the driving range of a vehicle can be prolonged by decreasing the energy loss i.e., operating the components in their high-efficiency region. Therefore, it is necessary to perform Optimal Power Flow (OPF) in the operation of the e-powertrain.
