在这项研究中，设计和建模的混合风能光伏系统的目的是通过水电解制氢。每周的太阳辐射，风速和环境温度的萨汉德，伊朗的实际数据，用于性能模拟和分析的系统检查。使用了组件的详细模型。10 kW碱性电解槽模型，产生氢气，是基于经验电化学关系，热力学和传热理论的组合。该系统的运行采用帝国竞争群算法进行优化。优化的目标是最大限度地提高氢气产量，同时考虑最小产量的平均过剩功率。在仅使用风力涡轮机（WT）、光伏（PV）阵列以及它们的组合作为电源的三种不同条件下分析该系统，分别产生8297、4592和10，462摩尔的氢气。对于这一结果，并与其他仿真结果的分析，阐明了混合系统是更有用的这项研究。在混合形式下，光伏阵列的平均生产功率与标称功率的比值为0.247，WT为0.493，这表明WT在生产中更有效。(C)2014爱思唯尔有限公司版权所有。
In this study, design and modelling of hybrid wind-photovoltaic system is done for the purpose of hydrogen production through water electrolysis. Actual data for weekly solar irradiation, wind speed, and ambient temperature of Sahand, Iran, are used for performance simulation and analysis of the system examined. The detailed model of components is used. The 10 kW alkaline electrolyzer model, which produces hydrogen, is based on combination of empirical electrochemical relationships, thermodynamics, and heat transfer theory. The operation of this system is optimized using imperial competitive colony algorithm. The objective of optimization is to maximize hydrogen production, considering minimum production of average excess power. This system is analysed in three different conditions of using just wind turbine (WT), photovoltaic (PV) array, and combination of them as power source, producing hydrogen of 8297, 4592, and 10,462 mol, respectively. As for this result and with analysing other results of simulation, it is clarified that the hybrid system is more useful for this study. In hybrid form the ratio of average produced power to nominal power for PV array is 0.247 and for WT is 0.493 which demonstrates that WT is more effective in production. (C) 2014 Elsevier Ltd.
