Development and deployment of a realtime interface customer endpoint for enhancing grid stability and congestion management in the Dutch energy sector

The rapid energy transition in the Netherlands has intensified challenges related to grid stability and congestion management . To address these, Netbeheer Nederland, in collaboration with Dutch Distribution System Operators (DSOs) and market players, developed the Realtime Interface (RTI), a standardised communication system enabling real-time data exchange and dynamic power control between DSOs and Distributed Energy Resources (DERs) at the Point of Common Coupling (PoCC). This paper details the design, development, and validation of the Teleport Gateway, the first RTI-compliant customer endpoint. It translates DSO setpoints into actionable commands for DERs such as photovoltaic systems, wind turbines, and battery energy storage systems. It leverages the IEC 61850 protocol for communication and integrates market signals for grid balancing and congestion management. Field trials with Enexis and other DSOs demonstrated the Teleport's scalability, reliability, and compliance with regulatory standards. The RTI and Teleport highlights the importance of standardised protocols, collaborative stakeholder involvement, and cybersecurity in addressing energy transition challenges.
