摘　　要：随着新能源的快速发展,为了满足供电系统高可靠性的需求,如何实现多点新能源之间的协同控制,成为研究的热点问题。文章提出一种计及一致性的多点新能源发电制氢系统协同控制策略,一方面,基于负载需求以及新能源发电功率,动态调整各台虚拟同步发电机的输出功率,使电解槽在参与电网频率调节的同时能够提升整体的制氢效率;另一方面,通过建立频率一致性算法,维持并联系统各节点间的频率同步,确保系统稳定运行。其次,考虑多点协同控制在交互的过程中存在的通信延时问题,在原有协同控制策略的基础上,引入模型预测控制,提前预测并补偿延时造成的控制误差,来提升系统在通信延时情况下的鲁棒性。最后,通过仿真验证所提控制策略的有效性。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.
