I’m excited to share that our paper “On the Damping and Coupling Impacts of DC Fault-Limiting Reactors in Multi-Terminal DC Grids” has been published in the International Journal of Electrical Power & Energy Systems. In this work, we investigate how DC fault-limiting reactors (DCRs), used for HVDC protection, affect the small-signal stability and dynamic coupling among converter stations in MMC-based multi-terminal DC grids. We analyze the critical operating points under different system design parameters and propose a dedicated control solution to mitigate the risk of small-signal instability without restricting operational flexibility. In addition, we show that the presence of DCRs fundamentally impacts the dynamic coupling and DC voltage support between converter stations, challenging the commonly used equivalent-capacitance assumption. This research was conducted at SuperGrid Institute and supported by the InterOPERA EU project, contributing to the broader effort of improving interoperability and dynamic performance of future multi-vendor HVDC grids. I would like to sincerely thank my co-authors and supervisors Kosei Shinoda, Jing DAI, and Seddik BACHA for their valuable guidance and collaboration throughout this study. 🔗 Read the full article https://lnkd.in/eeDWNJeb

Our 4th technical workshop yesterday brought together the members of the Stakeholder Committee to discuss two pillars for the success of the Multi-Vendor multi-terminal demonstrator: 🔹 The risk assessment and procurement strategy - presented by @Laurens Busschaert from Elia Group 🔹 The legal basis for procurement procedure - presented by Emanuele Marsella from Terna SpA 🔹And the Multi-Party Cooperation Framework - presented by René Lindeboom from Ørsted A big thank you to all participants for your contributions! 👏

🚀The detailed functional specifications for the InterOPERA Demonstrator are now live! We are thrilled to announce the successful completion of the final specifications. This milestone marks a pivotal step forward in defining the foundations for a multi-vendor, multi-terminal HVDC system, with detailed functional specifications developed through strong coordination, continuous collaboration, and a series of productive workshops over the past year. The document covers functional specifications for the InterOPERA demonstrator, built upon the functional frameworks and system design studies carried out within the project. The specifications include: 🔹Coordinated DC grid control 🔹 AC/DC converter stations 🔹 DC switching stations 🔹 DC connected power park modules 👉 Read it here: https://lnkd.in/dWDNirJR A huge thank you and congratulations to Siemens Energy team, especially Patrick Düllmann, and all the teams involved in delivering the specifications for all subsystems across #InterOPERA's project. Let's keep the collaboration and commitment going as we move forward! Sébastien SILVANT Heitor Farias Bence Hátsági Laurent Chédot Laurids Dall Riccardo Longo #HVDC #Innovation #SystemIntegration

📢 Publication alert! Our three-paper series on Multi-Terminal HVDC grid design studies is now available! As we transition from point-to-point links to expandable, multi-terminal, multi-vendor HVDC grids, having a generic, technology-agnostic study process becomes crucial. Within InterOPERA EU, the project has delivered a three-level study package addressing aspects of early-stage design: 🔹Load flow study & contingency analysis- Validates continuous operating ranges and defines configuration-specific operational settings for the primary DC voltage control scheme, ensuring N-1 compliance. 🔹Dynamic studies – Quantifies maximum DC voltage excursions across various operating conditions and contingencies to define required dynamic bands for normal operation. 🔹Transient studies – Assesses maximum short-circuit currents and overvoltages following DC faults, while offering insights into insulation coordination and DC fault ride-through requirements. 👉 Check the full publications here: https://lnkd.in/dWDNirJR Thank you to the authors!
