WT system model parameters.

In recent times, renewable energy systems (RESs) such as Photovoltaic (PV) and wind turbine (WT) are being employed to produce hydrogen. This paper aims to compare the efficiency and performance of PV and WT as sources of RESs to power polymer electrolyte membrane electrolyzer (PEMEL) under different conditions. The study assessed the input/output power of PV and WT, the efficiency of the MPPT controller, the calculation of the green hydrogen production rate, and the efficiency of each system separately. The study analyzed variable irradiance from 600 to 1000 W/m2 for a PV system and a fixed temperature of 25°C, while for the WT system, it considered variable wind speed from 10 to 14 m/s and zero fixed pitch angle. The study demonstrated that the applied controllers were effective, fast, low computational, and highly accurate. The obtained results showed that WT produces twice the PEMEL capacity, while the PV system is designed to be equal to the PEMEL capacity. The study serves as a reference for designing PV or WT to feed an electrolyzer. The MATLAB program validated the proposed configurations with their control schemes.

近年来，光伏（PV）、风力涡轮机（WT）等可再生能源系统（RESs）被用于制氢。本文旨在对比不同工况下，以光伏、风力涡轮机作为可再生能源系统供电源，为质子交换膜电解槽（PEMEL）供电的效率与性能。本研究评估了光伏与风力涡轮机的输入/输出功率、最大功率点跟踪控制器（Maximum Power Point Tracking, MPPT）的效率，计算了绿氢产率，并分别分析了两套系统各自的效率。针对光伏系统，本研究设置了600~1000 W/m²的可变辐照度与25℃的固定温度；针对风力涡轮机系统，则考虑了10~14 m/s的可变风速与固定零桨距角。研究结果表明，所采用的控制器具备有效性强、响应快速、计算量低且精度极高的优势。所得结果显示，风力涡轮机的产电能力为质子交换膜电解槽额定容量的两倍，而光伏系统的设计容量则与电解槽额定容量相当。本研究可为设计用于为电解槽供电的光伏或风力涡轮机系统提供参考依据。本研究通过MATLAB程序对所提出的系统配置及其控制策略进行了验证。
