摘要:

混合动力总成(HPT)通常涉及多种能源来源,往往包括能源存储系统/电池(ESS)。因此,电池退化风险和能源存储元件的可靠性在设计高效混合动力总成时构成了主要挑战。本文提出了一种能源管理策略,该策略能够自适应地将功率需求在发动机和电池组之间分配,考虑到电池退化。将电池退化模型直接纳入底层优化问题中存在多个挑战:1)任何合理的退化模型由于其复杂性,都会导致一个复杂的优化问题,这在实时实现中是不切实际的;2)模型包含大量的时间变化参数,这些参数只能通过破坏性实验程序确定。因此,必须设计出合理的启发式方法来捕捉电池的使用退化情况。本文考虑的其中一种启发式方法是电池提取的绝对功率。然后开发了一种分布式模型预测策略,以协调功率分配,以在提高效率的同时降低由于电池退化导致的故障风险。设计的EM策略通过三种不同混合动力总成的真实模拟得到验证:混合道路车辆(例如:混合动力汽车(HEV))、混合地面车辆(例如:动态定位混合舰船(DPS))和混合空中车辆(例如:混合动力飞机(HEA))。结果表明,该能源管理策略在管理电池退化方面是有效的。

英文摘要:

Hybrid power trains (HPT) run on multiple energy sources, often involving energy storage systems/batteries (ESS). As a result, the risk of battery degradation and the reliability of energy storage elements pose a major challenge in designing an energy-efficient hybrid power train. This paper presents an energy management strategy that adaptively splits power demand between the engine and the battery pack in a hybrid power train taking into account the battery degradation. Incorporating the battery degradation model directly into the underlying optimization problem is challenging on multiple fronts: 1) Any reasonable degradation model will, due to its complexity, result in a complicated optimization problem that is impractical for real-time implementation 2) the models contain a lot of time-varying parameters that can only be determined through destructive experimental procedures. As a result, it is essential to devise heuristics that reasonably capture the degradation per usage of the batteries. One such heuristic considered in this paper is the absolute power extracted from the battery. A distributed model predictive strategy is then developed to coordinate the power split to maximize efficiency while mitigating the failure risk due to battery degradation. The designed EM strategy is demonstrated through a realistic simulation of three different hybrid power trains: hybrid road vehicles (for example: a hybrid electric vehicle (HEV)), hybrid surface vehicles (for example: dynamically positioned hybrid ships (DPS)), and hybrid aerial vehicles (for example: hybrid electric aircraft (HEA)). The results show the effectiveness of the energy management strategy in managing battery degradation.
