In the last decade, there have been several initiatives for the deployment of cross-Mediterranean HVDC (High Voltage Direct Current) links to enable the transmission of electrical power from renewable energy sources between North Africa and Europe. These initiatives were mainly driven by the potential economic, environmental and technical benefits of these HVDC interconnections. In previous studies on these projects, some technical aspects of critical importance have not been addressed or studied in sufficient detail. One of these key aspects relates to the impact and possible benefit of these HVDC links on the dynamic performance of the European system which is the major focus of this paper. Several issues relating to the dynamic performance of the system are addressed here. Based on the experience gained from existing AC/DC projects around the world, this paper shows that the HVDC links between North Africa and Europe can greatly improve the dynamic performance of the European system especially in the southern regions. In addition, some challenges on the operation and control of these HVDC links are highlighted and solutions to overcome these challenges are proposed. This review paper, therefore, serves as a preliminary study for further detailed investigation of specific impacts or benefits of these interconnections on the overall performance of the European system.

在过去的十年中，已经采取了一些计划来部署跨地中海的HVDC（高压直流电）链路，以使可再生能源中的电力在北非和欧洲之间传输。这些举措主要是由这些高压直流输电互连的潜在经济，环境和技术优势推动的。在先前对这些项目的研究中，一些至关重要的技术方面尚未得到充分的解决或研究。这些关键方面之一涉及这些HVDC链路对欧洲系统动态性能的影响和可能带来的好处，这是本文的重点。这里讨论了与系统动态性能有关的几个问题。根据从全球现有AC / DC项目获得的经验，本文表明，北非和欧洲之间的高压直流输电线路可以极大地改善欧洲系统的动态性能，尤其是在南部地区。此外，重点介绍了这些HVDC链路的操作和控制方面的一些挑战，并提出了克服这些挑战的解决方案。因此，本综述文件是一项初步研究，旨在进一步详细研究这些互连对欧洲体系整体绩效的特定影响或益处。重点介绍了这些HVDC链路的操作和控制方面的一些挑战，并提出了克服这些挑战的解决方案。因此，本综述文件是一项初步研究，旨在进一步详细研究这些互连对欧洲体系整体绩效的特定影响或益处。重点介绍了这些HVDC链路的操作和控制方面的一些挑战，并提出了克服这些挑战的解决方案。因此，本综述文件是一项初步研究，旨在进一步详细研究这些互连对欧洲体系整体绩效的特定影响或益处。
