摘要

为提高可再生能源耦合制氢系统的安全性和能量转换效率,提出基于Petri网的多电源场景双渠道制氢系统优化控制方法。根据不同制氢设备对波动输入的适应能力差异性,构建由碱性电解槽、质子交换膜电解槽和燃料电池组成的多电源场景混合制氢系统架构;采用鲁棒经验模态分解算法对风光耦合输出功率进行分解,根据电解槽承载的功率下限值和电解槽冷启动时间,制定双渠道电解槽启停控制规则,建立基于Petri网的双渠道电解槽优化控制模型。通过某风电和光伏机组实际运行数据仿真实例验证所提方法的有效性。与单一渠道制氢系统相比,采用双渠道制氢可使能量转换效率提升至61.52%,可降低碱性电解槽的启停次数,提高制氢系统的安全性和经济性。

Abstract

To enhance the safety and energy conversion efficiency of renewable energy-coupled hydrogen production systems, this study proposes an optimization control method for dual-channel hydrogen production systems in multi-source scenarios based on Petri nets. Considering the varying adaptability of different hydrogen production equipment to fluctuating inputs, a hybrid hydrogen production system architecture comprising alkaline electrolyzers, proton exchange membrane electrolyzers, and fuel cells is constructed. A robust empirical mode decomposition algorithm is employed to decompose the coupled wind-solar output power. Based on the lower limit value value of the power carried by the electrolyzers and cold start time of the electrolyzers, dual-channel electrolyzer start-stop control rules are formulated, establishing a Petri net-based optimization control model for dual-channel electrolyzers. The effectiveness of this method is validated through simulation examples using actual operational data from a wind and photovoltaic power plant. Compared to single-channel hydrogen production systems, the dual-channel approach enhances energy conversion efficiency to 61.52%, reduces alkaline electrolyzer start-stop frequency, and improves both safety and economic performance of the hydrogen production system.
