提出了一种新的风电场与制氢系统的协调控制方法。在WF和HPS连接到电网的并网系统中，WF可以向电网供电，从而在HPS中产生氢气。此外，当HPS从输出盈余产生氢时，WF的输出波动可以被减轻。并网系统的目的是充分平滑WF输出波动，不断产生氢气，并保持HPS中的高容量因子。所提出的协调控制实现了WF输出的缓解和HPS中的高容量因子。其核心思想是1）利用风力发电机的动能和2）HPS的虚拟放电。WF输出的波动分量由WF和HPS两者补偿。建议的协调控制器使我们能够生产氢气不断在HPS与低额定功率。通过与传统方法的比较分析，验证了所提出的协调控制的优势，通过模拟使用真实的风数据。
This paper proposes a novel coordinated control method of wind farms (WFs) and hydrogen production systems (HPSs). In a grid-connected system where the WF and the HPS are connected to the grid, the WF can supply the power to the grid, producing hydrogen in the HPS. Moreover, the output fluctuation of the WF can be mitigated when the HPS produces hydrogen from the output surplus. The purpose of the grid-connected system is to smooth the WF output fluctuation sufficiently, produce hydrogen constantly, and maintain a high capacity factor in the HPS. The proposed coordinated control achieves the mitigation of the WF output and the high capacity factor in the HPS. The key ideas are 1) utilizing the kinetic energy of wind generators and 2) virtual discharge of the HPS. The fluctuation components of the WF output are compensated by both the WF and the HPS. The proposed coordinated controller enables us to produce hydrogen constantly in the HPS with a low-rated power. The advantage of the proposed coordinated control is verified by a comparative analysis with conventional methods through simulations using real wind data.
