With the rapid development of renewable energy

how to achieve cooperative control among multiple renewable energy sources to meet the high-reliability requirements of power supply systems has become a hot research topic. In this paper a kind of cooperative control strategy for a multi-point renewable energy power-to-hydrogen system that takes consistency into account is proposed. On one hand

based on load demand and renewable energy generation power

the output power of each virtual synchronous generator (VSG) is dynamically adjusted to enable the electrolyzer to participate in grid frequency regulation while improving the overall hydrogen production efficiency. On the other hand

the stable operation of the system is maintained by setting up a frequency consistency algorithm and maintaining frequency synchronization among the nodes of the parallel system. Furthermore

considering the communication delay issues that arise during the interaction process of multi-point cooperative control

the model predictive control is introduced on the basis of the original cooperative control strategy to predict and compensate for control errors in advance due to delays

thereby enhancing the system’s robustness under communication delay conditions. Finally

the effectiveness of the proposed control strategy is verified through simulation.
