摘要

本文研究了交流电网与直流系统之间的动态相互作用。在这项工作中，我们专注于MMC-HVDC连接海上风电场和交流系统。陆上变流器在直流侧以直流电压控制方式控制，在交流侧以并网方式控制。本文阐述了直流电压环设计在成网模式下控制MMC的重要性及其对MMC内能的影响。在结论部分，对支持直流电压的不同潜在解决方案提出了一些建议。

AC/DC Dynamic Interactions of MMC-HVDC in Grid-Forming for Wind-Farm Integration in AC Systems

This paper studies the dynamic interactions between the AC grids and the DC system. In this work, we focus on MMC-HVDC links interconnecting offshore wind farms and AC systems. The onshore converter is controlled in DC-voltage control mode on the DC side and in grid-forming on the AC side. The authors show the importance of DC-voltage loop design when controlling the MMC in grid-forming mode and its consequences on the MMC internal energy. In the conclusion, some recommendations are made regarding different potential solutions for supporting the DC voltage.
