风储耦合多碱性电解制氢功率-状态滚动优化控制OA

To address the issues of poor dynamic adaptability in multi-unit coordination during electrolytic hydrogen production,as well as low efficiency and economic performance in the operation of wind-energy storage-hydrogen coupled systems,this paper proposes a three-stage power-state rolling optimization control strategy.First,in the initial stage,this paper develops a battery wind power smoothing strategy based on empirical mode decomposition to enhance the operational stability of the hydrogen production system.Second,based on the smoothed wind power,a multi-unit collaboration optimization model is developed in the second stage,aiming to minimize wind power curtailment,reduce the frequency of unit startups and shutdowns,maximize hydrogen production,and equalize operating time and power fluctuation carrying capacity,thereby optimizing the power distribution among hydrogen production units.In the third stage,correction strategies for the cold start process,standby,and shutdown operating states of the alkaline electrolysis unit are presented,and the optimal production plan for the system is formulated.Finally,through comparative analysis of daily and annual case studies with traditional strategies,the proposed method's effectiveness and superiority are validated in terms of wind power utilization,unit startup and shutdown frequency,operational balance,system efficiency,and economic performance.
