Abstract

In alkaline water electrolysis （AWE） systems powered by renewable energy

elevated hydrogen to oxygen （HTO） concentration caused by power fluctuations poses safety risks

and improper operating parameters lead to reduced system efficiency. To address these issues

this study proposes a coordinated control method based on the feasible domain of operating parameters. First

the influence of temperature variations and shunt currents on the AWE system under fluctuating operating conditions is analyzed

and models for HTO concentration and system efficiency are established

followed by a parameter sensitivity analysis. Then

the feasible domain of AWE operating parameters is determined based on the safety boundaries of current density

pressure

and electrolyte circulation flow rate. Finally

a feasible-domain-based multi-objective optimization control method is proposed for AWE operation under fluctuating conditions

and its effectiveness is verified in photovoltaic and wind power hydrogen production scenarios. The results demonstrate that the proposed method effectively extends the system’s operating hours

increases hydrogen production

enhances the adaptability of the AWE system to renewable energy

and achieves safe and efficient hydrogen production.
