摘　　要：通过分析电解制氢效率与制氢功率的关系,提出一种基于分段模糊控制电解槽阵列效率提升的策略,基于大规模风-氢耦合系统应用场景,建立考虑风电制氢效率的风电制氢系统优化调度模型,并采用人工蜂群算法求解最优制氢功率。仿真结果表明,所提出的控制策略不仅可保证电解槽的安全运行,同时能提高电解槽的制氢效率,为电解制氢系统在电力系统中的大规模应用提供理论依据。最后,在此基础上,加入电解槽阵列的模块化优化策略,使建立的分段模糊控制器能够统筹安全性、经济性、能效性,以期为氢能在电力系统中的大规模应用提供理论依据。By analyzing the relationship between the efficiency of electrolyzer and hydrogen production power,this paper proposes a strategy to improve the efficiency of electrolyzer array based on subsection fuzzy control.Based on the scenario of large-scale wind power to hydrogen system,an optimal adjustment model of wind power to hydrogen system considering the efficiency of electrolyzer is established,and the optimal power of hydrogen production is calculated by an artificial bee colony algorithm.The simulation results show that the control strategy proposed in this paper can not only ensure the operation safety of the electrolyzer,but also improve the efficiency of the electrolyzer,providing a theoretical basis for the large-scale electrolyzer of application in the power system.Finally,based on the previous research results,a modular optimization strategy is added to the electrolyzer,enabling the established subsection fuzzy controller to coordinate the safety,economy and energy efficiency,and providing a theoretical basis for the large-scale application of hydrogen energy in the power system.
