Abstract：Hydrogen energy，characterizedbyitsclean nature and high energy density，is a key technical pathwayforthe large-scale integration of renewable energy andclean energyutilization.Toaddresstheeconomic challenges of photovoltaic（PV）-coupled electrolytic hydrogen production systems，a cordinated operational strategy foroptimal power alocation based onvarying electricity prices is proposed.Mathematical models for thePV system and thealkaline electrolyzer are developed，and the nonlinear dynamic relationship between the electrolyzer's hydrogen production rate and its powerconsumption isanalyzed.On this basis，with the objective of maximizing total system revenue，the proposed strategy utilizes electricity price diferences to dynamicallyallcate energy betweengrid salesand electrolytic hydrogen production.Theresultsshow that thestrategy efectively optimizes power allocation according to electricity prices and PV power output，thereby achieving revenue maximization in differenttimeperiods.Thiswork provides technical supportfortheeconomicoperationof PV-coupled hydrogen production systems.
