摘要： 利用可再生能源大规模制取氢气是实现可再生能源消纳和平抑波动的重要技术手段,针对大规模具有间歇性可再生能源制氢系统的优化运行问题,提出了一种并联制氢装置的效率优化控制方法。首先建立了制氢装置的效率模型,其次通过构建多并联制氢装置的效率优化目标函数和约束条件,采用穷举算法优化不同输入功率时各并联制氢装置的最优功率分配值。最后通过MATLAB仿真验证该策略的有效性和可行性,并与功率均分、分级投切方式下的运行效率比较,结果表明,提出的效率优化控制可有效提高波动功率下并联系统的运行效率。

Abstract: Large scale hydrogen production from renewable energy is an important technical means to achieve renewable energy consumption and suppress fluctuations. Aiming at the optimal operation of large-scale intermittent renewable energy hydrogen production system, an efficiency optimization control method of parallel hydrogen production units is proposed. Firstly, the efficiency model of hydrogen production units is established. Secondly, by constructing the efficiency optimization objective function and constraints of multiple parallel hydrogen production units, the optimal power distribution value of each parallel hydrogen production device at different input power is optimized by exhaustive optimization algorithm. Finally, the effectiveness and feasibility of the method are verified by MATLAB simulation, and its operating efficiency are compared with the power sharing and hierarchical switching modes. The results show that the efficiency optimization control method can effectively improve the operation efficiency of the parallel system under fluctuating power.

Key words: electrolytic hydrogen production, parallel connection, hydrogen production efficiency, optimize control, power distribution
