针对可再生能源的波动性与不确定性,以及氢储能在跨季节长时间储能方面的优势与波动工况对电解槽运行寿命的影响,提出了一种考虑电解槽梯度组合与混合工况制氢策略的微电网双层容量规划方法。首先,采用多元Copula函数表征源荷相关性,建立基于季节性源荷不确定性的典型场景;其次,结合年历史净负荷功率概率分布特性与碱性电解槽运行特性,构建电解槽组合梯度容量约束及多级混合工况制氢策略。在此基础上,建立上层以储能设备配置总成本最低、下层以年运行成本最小为目标的双层容量规划模型。最后,通过算例分析验证所提方法的有效性。结果表明,所提策略能够提升系统经济性及电解槽制氢效率,并有效抑制功率波动对电解槽运行的不利影响。
In response to the volatility and uncertainty of renewable energy,as well as the advantages of hydrogen storage for long-term cross-seasonal energy storage and the impact of fluctuating operating conditions on electrolyzer lifespan,this paper proposes a bi-level capacity planning method for microgrids that considers a combined gradient and hybrid operating mode strategy for electrolyzers.First,a multivariate Copula function is employed to characterize the correlation between source and load,establishing typical scenarios based on seasonal source-load uncertainty.Second,combining the annual historical net load power probability distribution characteristics and the operational features of alkaline electrolyzers,capacity constraints for the electrolyzer cluster with gradients and a multi-level hybrid operating mode strategy for hydrogen production are constructed.Based on this operational strategy,a bi-level capacity planning model is established,with the upper level aiming to minimize the total cost of energy storage equipment configuration and the lower level targeting the minimization of annual operational costs.Finally,case studies are conducted to validate the effectiveness of the proposed method.The results show that the proposed strategy can enhance system economics,improve hydrogen production efficiency of electrolyzers,and effectively mitigate the adverse effects of power fluctuations on electrolyzer operation.
