燃料电池混合动力列车速度与能量管理系统的凸优化

Convex Optimization of Speed and Energy Management System for Fuel Cell Hybrid Trains

摘要:

我们希望通过优化氢混合动力列车的运行,最大限度地减少氢燃料的消耗。考虑的动力系统是燃料电池充电维持混合动力。凸优化用于计算最佳速度和能量管理轨迹。障碍物法用于快速求解优化问题,整个行程约为数十秒。模拟显示,当两个轨迹-速度和能量管理-在单个优化问题中同时优化时,与以顺序方式分别优化-在优化速度之后优化能量管理相比,燃料消耗大大减少。它的结论是,并行方法大大受益于其整体动力系统的知识,同时优化所有的轨迹在一个单一的优化问题。

英文摘要:

We look into minimizing the hydrogen fuel consumption of hydrogen hybrid trains by optimizing their operation. The powertrain considered is a fuel cell charge-sustaining hybrid. Convex optimization is utilized to compute optimal speed and energy management trajectories. The barrier method is used to solve the optimization problems quickly on the order of tens of seconds for the entire journey. Simulations show a considerable reduction in fuel consumption when both trajectories -- speed and energy management -- are optimized concurrently within a single optimization problem in comparison to being optimized separately in a sequential manner -- optimizing energy management after optimizing speed. It is concluded that the concurrent method greatly benefits from its holistic powertrain knowledge while optimizing all trajectories together within a single optimization problem.
