基于DP-ECMS的插电式混合动力城市客车能量管理策略研究

摘要

以一款气电型插电式混合动力城市客车(PHEV)为研究对象,针对能量管理中的最小能耗问题分别应用电量消耗电量维持(CD-CS)策略、动态规划(DP)、等效能耗最小化策略(ECMS)和自适应等效能耗最小化策略(A-ECMS)进行中国典型城市工况仿真.在对上述几种能量管理策略仿真结果分析的基础上,提出一种将动态规划与等效能耗最小化策略相结合的DP-ECMS策略.结果表明:DP-ECMS的能耗特性接近动态规划,同时具有等效能耗最小化策略的实时性特点,为PHEV的能量管理提供了参考.%Aiming at the issue of minimum energy consumption in energy management, four strategies of charge-depletion-charge-sustaining ( CD-CS ) , dynamic programming ( DP ) , equivalent consumption minimization strategy ( ECMS) and adaptive equivalent consumption minimization strategy ( A-ECMS) are adopted respectively to conduct a simulation on a gaseous plug-in hybrid electric bus with Chinese city driving cycle. On the basis of analy-sis on simulation results, a DP-ECMS strategy combining DP with ECMS strategy is put forward. The results indicate that DP-ECMS strategy has an energy consumption characteristic close to that of DP , with a real time feature of EC-MS, providing a good reference for the energy management of PHEV.
