| “双碳”目标下，高比例新能源装机带来的消纳难、波动强等问题亟待解决，具备可调节能力的电解槽负荷可实现与新能源出力的双向匹配，同时，离网制氢所产出的为全寿命周期零碳排的绿氢，是实现“双碳”战略的重要推动力。因此提出一种考虑混合电解槽的风-光-储离网制氢系统容量配置优化方法。首先，对系统的电源侧、制氢侧中的关键部分设备进行建模分析；其次，以系统制氢成本最低为优化目标，构建风-光-储离网制氢系统优化模型；最后，算例以我国西北某地区风电和光伏出力数据为基础进行了仿真分析，结果表明：混合电解槽协同运行策略相比单一电解槽能够降低制氢成本、减少电解槽启停次数、减少新能源弃电，验证了所提模型和方法的可行性和有效性。 |
| 英文摘要: |
| Under the goal of“dual carbon”, the high penetration of renewable energy generation brings about critical challenges such as integration difficulties and strong power fluctuations, which urgently require solutions. Electrolyzer loads with adjustable capacity can achieve bidirectional matching with renewable energy output. Meanwhile, off-grid hydrogen production yields green hydrogen with zero carbon emissions throughout its life, serving as a key driver for achieving the“dual carbon”strategy. Therefore, an optimal capacity configuration method for an off-grid wind-solar-storage hydrogen production system considering hybrid electrolyzers is proposed. First, modeling and analysis are conducted for key components on the power supply side and hydrogen production side of the system. Second, with the objective of minimizing hydrogen production costs, an optimization model for the off-grid wind-solar-storage hydrogen production system is constructed. Finally, a case study is performed based on wind and PV output data from a region in Northwest China. Simulation results demonstrate that the coordinated operation strategy of hybrid electrolyzers, compared to a single electrolyzer, can reduce hydrogen production costs, decrease the start-stop cycles of electrolyzers, and mitigate renewable energy curtailment, thereby verifying the feasibility and effectiveness of the proposed model and method. |
