Thus, deploying redundant hardware for both local and wide area communication, along with protocols that leverage these redundancies for automatic and timely failovers, is fundamental. This paper presents a comprehensive overview of key protocols (PRP/HSR, MPLS-TP, and MPTCP) which offer robust recovery mechanisms. Additionally, it provides a specific concept and topology that effectively combine the presented protocols to ensure resilient communication from the control center to substation devices. ven2us Proceedings of the CIRED Chicago Workshop 2024 on Resilience of Electric Distribution Systems, November 7-8, 2024, Chicago, USA Chicago CIRED Chicago Workshop 2024 on Resilience of Electric Distribution Systems November 7-8, 2024 accepted 1 Ina BereniceFink MarkusDahlmanns GerritErichsen KlausWehrle inproceedings 2024-dahlmanns-cired 2024 6 19 The increasing demands on the power grid require intelligent and flexible solutions that ensure the grid's stability. Many of these measures involve sophisticated communication between the control center and the stations that is not efficiently realizable using traditional protocols, e.g., IEC 60870-5-104. To this end, IEC 61850 introduces data models which allow flexible communication. Still, the specification leaves open how DSOs should interconnect their stations to realize resilient communication between the control center and station devices. However, DSOs require such communication to adapt modern solutions increasing the grid's capacity, e.g., adaptive protection systems. In this paper, we present our envisioned network and communication concept for future DSO's ICT infrastructures that enables the control center to resiliently and flexibly communicate with station devices. For resilience, we suggest interconnecting each station with two distinct communication paths to the control center, use MPLS-TP and MPTCP for fast failovers when a single link fails, and mTLS to protect the communication possibilities against misuse. Additionally, in accordance with IEC 61850, we envision the control center to communicate with the station devices using MMS by using the station RTU as a proxy. ven2us Proceedings of the CIRED workshop on Increasing Distribution Network Hosting Capacity 2024, June 19-20, 2024, Vienna, Austria Vienna CIRED workshop on Increasing Distribution Network Hosting Capacity 2024 June 19-20, 2024 10.1049/icp.2024.2096 1 MarkusDahlmanns Ina BereniceFink GerritErichsen GuosongLin ThomasHammer BurkhardBorkenhagen SebastianSchneider ChristofMaahsen KlausWehrle poster 2024-fink-sul 2024 3 5 19 ven2us VDE ETG/FNN-Tutorial 2024 Schutz- und Leittechnik, March 05-06, 2024, Leipzig, Germany Leipzig, Germany VDE ETG/FNN-Tutorial 2024 Schutz- und Leittechnik March 05-06, 2024 1 Ina BereniceFink MarkusDahlmanns KlausWehrle
