Abstract

This study introduces an advanced nonlinear optimization-based energy management system (EMS) specifically designed for modular Proton Exchange Membrane Water Electrolyzers (PEMWE) under fluctuating solar energy conditions. To optimize system efficiency, reduce degradation, and maintain balanced stack operation, the Rotary Power Allocation Strategy (RPAS) employs a dynamic power distribution method that allocates power among multiple stacks based on current demand. A validated electrochemical model calibrated through laboratory experiments and genetic algorithm optimization serves as the foundation for the analysis. Benchmarking in this study has demonstrated the superiority of the proposed strategy to established EMS methods, such as rule-based, fuzzy logic, composite optimization, and decentralized multi-agent scheduling. In terms of system efficiency, it has been demonstrated that there is an increase of 63 % in system efficiency, a greater hydrogen yield exceeding 4200 kg per year, and a considerable reduction in stack voltage degradation. The strategy effectively addresses key limitations associated with conventional EMS approaches, ensuring consistent and equitable stack usage, thus providing a robust, scalable solution for renewable energy-driven hydrogen production.

波动太阳能输入下模块化质子交换膜水电解槽的能量管理：约束非线性优化方法

本文介绍了一种先进的非线性优化能量管理系统（EMS），该系统是专门为太阳能波动条件下的模块化质子交换膜水电解槽（PEMWE）设计的。RPAS （Rotary Power Allocation Strategy）采用动态的功率分配方法，根据当前需求在多个堆栈之间分配功率，以优化系统效率，减少系统退化，并保持堆栈的均衡运行。通过实验室实验和遗传算法优化校准的验证电化学模型作为分析的基础。本研究的基准测试表明，该策略相对于现有的基于规则、模糊逻辑、复合优化和分散多智能体调度等EMS方法具有优越性。在系统效率方面，已经证明系统效率提高了63 %，氢气产量超过每年4200 kg，并且大大减少了堆叠电压退化。该战略有效地解决了与传统EMS方法相关的关键限制，确保了一致和公平的堆栈使用，从而为可再生能源驱动的氢气生产提供了一个强大的、可扩展的解决方案。

期刊介绍： Applied Energy serves as a platform for sharing innovations, research, development, and demonstrations in energy conversion, conservation, and sustainable energy systems. The journal covers topics such as optimal energy resource use, environmental pollutant mitigation, and energy process analysis. It welcomes original papers, review articles, technical notes, and letters to the editor. Authors are encouraged to submit manuscripts that bridge the gap between research, development, and implementation. The journal addresses a wide spectrum of topics, including fossil and renewable energy technologies, energy economics, and environmental impacts. Applied Energy also explores modeling and forecasting, conservation strategies, and the social and economic implications of energy policies, including climate change mitigation. It is complemented by the open-access journal Advances in Applied Energy.
