In order to guarantee the stable and efficient operation of the new energy electrolysis hydrogen production system
a hydrogen production system efficiency model was first constructed
encompassing the PEM electrolyser
hydrogen production power supply
compression
drying
circulating cooling
and other auxiliary links. A power-adaptive control strategy based on the optimal efficiency of the hydrogen production system was proposed based on this model. The strategy takes the optimal efficiency of the hydrogen production system as the goal and combines it with the power control of the hydrogen production power supply. Matlab/Simulink simulations was carried out in order to facilitate a comparison of the efficiency curves of the hydrogen production system under the chain distribution strategy
the average distribution strategy and the proposed optimization strategy. The results demonstrate that the strategy proposed in this paper serves to enhance the application range of the hydrogen production system for high-efficiency work and to improve the utilization of new energy.
