With the low-carbon

clean energy transition

requires an electrolyzer array formed by multiple electrolyzer tanks is required in large-scale wind power hydrogen generation system

and power distribution and state switching of the electrolyzer array are performed to adapt to the volatility of wind power output. In order to further improve the hydrogen production efficiency

hydrogen production

and overall operating life of the electrolyzer array

we proposed an optimized control method for wind power hydrogen electrolyzer array considering the operating characteristics of the electrolyzer. Based on the operating characteristics of the electrolyzer

the efficiency

hydrogen production

start-stop model

and lifetime decay model of the electrolyzer were established to quantify the system optimization targets and related evaluation indexes. An optimal control method for electrolyzer arrays based on historical operation data of electrolyzers is proposed. The operation duration of electrolyzers in each operation state is taken into account

the numbers of electrolyzers operating in overload

variable load

low load

standby

hot start

shutdown

and cold start states

are determined

respectively

and according to wind power

the power allocation and state switching of the electrolyzer arrays are performed. Quantitative analysis and comparison of the optimization results of different scenarios through a multi-scenario setup show that the optimization strategy proposed in this paper integrally improves the hydrogen production efficiency

operating life and hydrogen profits of the electrolyzer array

which verifies the effectiveness and economy of the proposed method.
