摘要
新能源电制氢是实现"2060碳中和"的关键技术之一。然而,新能源出力具有随机性,且制氢关键设备——质子交换膜(PEM)电解槽投资成本与运行成本高,因此如何为出力功率随机的新能源电站配置兼顾新能源弃电率与制氢系统经济性的PEM制氢系统具有重要意义。以风电制氢为例,首先提出随机波动输入下PEM电制氢系统全寿命周期的成本与收入模型,并以总收入、投资回收期与内部收益率为评估指标支撑系统的经济分析;基于此,针对"风电+PEM电制氢"系统,提出3种双层规划模型,上层模型分别以PEM电制氢系统全寿命周期总成本最小、总收入最大与内部收益率最大作为上层优化模型的目标函数,下层的优化目标为风电场的弃电率最小,并采用MATLAB遗传算法工具箱求解优化模型;最后,以某实际风力发电场为例,验证所提双层规划模型与风电制氢的有效性与经济可行性。
Hydrogen production from new energy electricity is one of the key technologies to achieve"2060 carbonneutral".However,the output of new energy power generation is random,and both the investment cost and operation cost of the flexible proton exchange membrane(PEM)electrolyzer are high.Therefore,how to configure the PEM hydrogen production system that takes into account both the abandonment rate of new energy power stations and the economy of hydrogen production system during the whole life cycle of new energy power stations with random power output has great significance.By taking hydrogen production by wind power system as an example,a wholelife cycle cost and income analysis model of the PEM electric hydrogen production system with stochastic fluctuation input is established in this paper,and the total income,investment payback period and internal rate of return(IRR)are used as the evaluation indexes to carry out economic analysis.On this basis,three double-layer planning models for the wind power-PEM electric hydrogen production system are proposed,with the smallest total cost,highest total income and largest internal rate of return of the PEM electric hydrogen production system over the whole life cycle as the objective function of the upper layer optimization model,and the smallest abandonment rate of the wind farm as the objective function of the lower layer optimization model.The MATLAB genetic algorithm tool box is applied to solve the optimization model.Finally,the effectiveness of the proposed two-level planning model and the economic feasibility of wind power hydrogen production are verified by taking an actual wind power plant station as an example.
