摘要：

为满足内河船舶的节能减排需求，并改善甲醇—电力混合动力系统能量管理策略，提出了一种融合了动态规划（DP）策略全局优化与实时控制的方法。基于台架试验数据，构建了反映油耗与排放特性的甲醇发动机准稳态模型，应用DP策略，来求解全局最优能量分配基准。采用NI PXIe硬件在环（HIL）测试平台，验证该策略的实时控制性能。结果表明：与确定规则（RB）策略相比，DP策略降低燃料消耗28.2%，HC、CO2、NOx的排放分别削减41.0%、42.6%、30.5%。从而，本研究为甲醇混合动力船舶提供了能量管理解决方案。

Abstract:

A method was proposed by using integrating globally optimized dynamic programming (DP) with real time control to address the energy-saving and emission-reduction needs of inland waterway vessels and to improve the energy management strategies for methanol electric hybrid propulsion systems. A quasi steady state model was developed based on bench test data to characterize the fuel consumption and emission patterns of the methanol engine. The DP strategy was employed to establish a globally optimal benchmark for energy allocation. The real time control performance of the strategy was validated by using an NI PXIe Hardware In the Loop (HIL) platform. The results show that the DP strategy reduces the fuel consumption by 28.2% and lowers the pollutant emissions of HC, CO2, and NOx by 41.0%, 42.6%, and 30.5% respectively, compared with the deterministic Rule Based (RB) strategy. Therefore, it provides a practical energy management solution for methanol fueled hybrid vessels.

Key words: hybrid propulsion systems, methanol-electric, energy management strategy, dynamic programming (DP) strategy, hardware-in-the-loop (HIL)
