The uncertainty in hydrogen demand leads to a misalignment between the actual operation of the hydrogen supply chains and its expected planning

resulting in unnecessary resource waste and increased economic costs. To address this issue

a collaborative control strategy is proposed to coordinate multi-regional production-inventory operations in the hydrogen supply chains. Firstly

considering internal and external factors such as hydrogen storage losses and transportation delays

a dynamic mechanism model of the hydrogen supply chain operation is established. Then

aiming at the goal of multi-regional coordination under uncertain demand

the operational mechanism model is transformed into a state-space control model. Subsequently

based on Lyapunov-Krasovskii time-delay stability analysis and large-scale system control theory

the multi-regional coordination performance of the production-inventory control system is analyzed

and a control strategy is designed. Finally

a case study of a three-region hydrogen supply in a power system is presented to demonstrate the effectiveness of the proposed strategy. The results show that the collaborative control enables multi-regional production-inventory operations to align with expected planning. Compared to scenarios without collaborative control

the average deviation in hydrogen production and storage is reduced by 82.2%

effectively lowering operational costs. Thus

this study provides a decision-support solution for enterprises in the hydrogen supply chains.
