电动汽车能量管理的机会约束Optimization

Chance Constrained Optimization for Energy Management in Electric Vehicles

摘要:

未来电动汽车的电动动力系统可以包括能量产生单元(例如,燃料电池和光伏模块),能量存储系统(例如,电池和超级电容器),能量转换单元(例如,双向DC/DC转换器和DC/AC逆变器)和电机,其可以在发电和电动模式下工作[1- 6]。能量管理系统负责以满足技术约束的方式操作上述组件。这个任务应该通过解决一个最优化问题来完成,这个问题的目标是使总的运行成本最小化[5]。最优化问题已被确定性方法[7]广泛解决,该方法考虑了有功-无功负荷曲线的预测值。然而,如图1(a)所示,不可能准确预测值,这意味着来自确定性方法的解决方案可能导致不可行的操作(即,违反约束)。因此,在考虑不确定参数时,应利用随机最优化方法[8]来寻找最优解策略。

英文摘要:

E-powertrain of future electric vehicles could consist of energy generation units (e.g., fuel cells and photovoltaic modules), energy storage systems (e.g., batteries and supercapacitors), energy conversion units (e.g., bidirectional DC/DC converters and DC/AC inverters) and an electric machine, which can work in both generating and motoring modes [1- 6]. An energy management system is responsible to operate the above-mentioned components in a way that the technical constraints are satisfied. This task should be accomplished by solving an optimization problem, which could aim at minimizing the total operation costs [5]. The optimization problem has been widely addressed by deterministic approaches [7], which take into account the forecasted values of active-reactive load profile. However, as shown in Figure 1 (a), it is impossible to accurately forecast the values, meaning that the solutions coming from deterministic approaches could lead to infeasible operations (i.e., constraint violations). Therefore, stochastic optimization approaches [8] should be utilized to fi nd optimal solution strategies while considering uncertain parameters.
