考虑平抑风光波动的ALK-PEM电解制氢系统容量优化模型
Capacity optimization model for an ALK-PEM electrolytic hydrogen production system considering the stabilization of wind and PV fluctuations
摘要
Abstract
To enhance wind power and photovoltaic utilization,electrolytic hydrogen production has gained attention.However,hydrogen energy is vulnerable to the fluctuations of these resources during production.Therefore,this paper proposes an alkaline-proton exchange membrane(ALK-PEM)capacity optimization model for hydrogen electrolysis to mitigate these fluctuations.First,the EMD algorithm is used to analyze the transient fluctuation characteristics of raw wind and PV.Supercapacitors are employed to smooth these fluctuations,ensuring safe and stable operation of the hydrogen production system.An EMD-based SC capacity allocation model is constructed for this purpose.Second,a capacity optimization model is proposed for the ALK-PEM electrolytic hydrogen production system.By combining proton exchange membrane(PEM)and Alkaline(ALK)electrolyzers,it replaces the single-type electrolyzer system.This approach considers different electrolyzer operational characteristics,thereby improving economic efficiency.Finally,the system's capacity planning is simulated using data from a wind farm and a photovoltaic power plant.This validates the proposed model's effectiveness in smoothing fluctuations,enhancing renewable energy utilization,and improving the system's overall economy.关键词
