摘要
为推动光伏电解水制氢技术商业化应用,提出了一种计及动态氢价机制的光伏电解水制氢调度策略。首先考虑余电上网和余电制氢两种运营模式,构建了光伏电解水制氢系统运营模型,在相关约束条件下,提出光伏电解水制氢系统调度策略,以整体最大化收益为目标,引入效用函数对加氢用户的满意度与售氢收益模型进行优化。其次以售氢收益和用户满意度最大为目标,通过NSGA2遗传算法求解得到最优动态氢价。最后采用CPLEX求解器得到不同场景下的最优调度策略方案,对优化后的运行结果及其经济性进行分析,并对比不同场景下的运行结果与经济效益。仿真结果表明,光伏电解水制氢调度策略采用动态氢价机制售氢能够有效提高售氢收益,并有序引导加氢需求,提高光伏电解水制氢的经济性。
To promote the commercial application of photovoltaic electrolysis hydrogen production technology,this study proposes a scheduling strategy for photovoltaic electrolysis hydrogen production that takes into account the dynamic hydrogen price mechanism.First,two operation modes,residual electricity grid connection and residual electricity hydrogen production,were considered.A photovoltaic electrolysis water hydrogen production system operation model was constructed,and under relevant constraints,a scheduling strategy for the photovoltaic electrolysis water hydrogen production system was proposed.The system aims to maximize overall revenue and introduces a utility function to optimize the satisfaction and sales revenue models of hydrogenation users.Second,to maximize sales revenue and user satisfaction,an optimal dynamic hydrogen price was obtained using the NSGA2.Finally,the CPLEX solver was used to obtain the optimal scheduling strategy scheme for different scenarios.The optimized operation results and their economic benefits were analyzed,and the operation results and economic benefits under different scenarios were compared.The simulation results show that the dynamic hydrogen pricing mechanism adopted in the photovoltaic electrolysis hydrogen production scheduling strategy can effectively increase hydrogen sales revenue,guide hydrogenation demand in an orderly manner,and improve the economic efficiency of photovoltaic electrolysis hydrogen production.
