摘要
为提高波浪滑翔机长期作业时的系统运行稳定性和能量利用效率,提出一种基于多目标优化方法的能量管理策略,构建波浪滑翔机能量管理数学模型,采用ε-约束法和线性加权法进行模型求解,设计仿真试验验证能量管理模型的有效性,并对不同任务下的能量调度结果进行分析研究。结果表明所提出的能量管理策略能够在满足系统运行约束的同时,实现对各电气设备的最优能量调度,提高波浪滑翔机的长期运行稳定性和能量利用效率。
In order to improve the system operation stability and energy utilization efficiency of wave glider during long-term operation,a multi-objective optimization-based energy management strategy(EMS)is proposed.The mathematical model of the wave glider energy management is constructed.The model is solved throughε-constraint and weighted sum method.The simulation test is designed to validate the effectiveness of the proposed EMS model and to analyze its performance in different task modes.The results indicate that the proposed EMS is able to achieve optimal power scheduling for each device while satisfying the underlying operation constraints,and improve the long-term operational stability and energy exploitation efficiency of the wave glider.
