The coordination between system operators is a key element for the decarbonization of the power system. Over the past few years, many EU-funded research projects have addressed the challenges of Transmission System Operators (TSO) and Distribution System Operators (DSO) coordination by implementing different data exchange architectures. This paper presents a review of the ICT architectures implemented for the main coordination schemes demonstrated in such projects. The main used technologies are analyzed, considering the type of data exchanged and the communication link. Finally, the paper presents the different gaps and challenges on TSO-DSO coordination related to ICT architectures that must still be faced, paying especial attention to the expected contribution of the EU-funded OneNet project on this topic.

用于 TSO-DSO 协调和数据交换的 ICT 架构：欧洲视角

系统运营商之间的协调是电力系统脱碳的关键要素。在过去几年中，许多欧盟资助的研究项目通过实施不同的数据交换架构解决了输电系统运营商 (TSO) 和配电系统运营商 (DSO) 协调方面的挑战。本文回顾了为此类项目中展示的主要协调方案实施的 ICT 架构。考虑到交换的数据类型和通信链路，分析了主要使用的技术。最后，本文介绍了仍然必须面对的与 ICT 架构相关的 TSO-DSO 协调方面的不同差距和挑战，特别关注欧盟资助的 OneNet 项目对该主题的预期贡献。
