摘要

针对光伏制氢(photovoltaic electrolysis，PVE)直接耦合系统容量配置研究将电解槽阵列视作静态结构，无法准确刻画系统预期收益的问题，该文提出一种基于改进遗传算法-遍历搜索法的PVE直接耦合系统双层容量优化配置方法。通过建立包含光伏电池、质子交换膜(proton exchange membrane，PEM)电解槽的PVE直接耦合系统模型，分析电解槽串并联动态变化对于系统性能影响。基于双层容量优化配置模型，在内层考虑电解槽阵列串并联结构动态调节机制，以产氢量最大为目标，优化典型日各时刻的电解槽串并联结构，外层以规划周期收益最高为目标，得到容量配置结果。以我国东北三省光辐照度数据为基础进行算例分析，结果表明，所提方法能够提升系统收益、降低制氢成本，该文可为光伏制氢系统的建设提供一定技术支撑。

Abstract

A dual-layer capacity optimization configuration method for direct coupled photovoltaic hydrogen (PVE) systems is proposed based on an improved genetic algorithm-traversal search method to address the inaccuracy in expected system revenue characterization due to static electrolyzer-array modeling. By establishing a PVE direct coupling system model that includes photovoltaic cells and proton exchange membrane (PEM) electrolytic cells

the impact of dynamic series-parallel reconfiguration of electrolyzers on system performance is analyzed. Based on a double-layer capacity optimization configuration model

the dynamic adjustment mechanism of the series-parallel structure of the electrolytic cell array is considered in the inner layer. With the goal of maximizing hydrogen production

the hourly series-parallel structure of the electrolytic cell on the typical day is optimized. The outer layer is designed with the goal of maximizing the cycle revenue

and the capacity configuration results are obtained. Based on the irradiance data from the three northeastern provinces of China

the results show that the proposed method can improve system revenue and reduce hydrogen production costs. This paper can provide some technical support for the construction of photovoltaic hydrogen production system.
