CIGRE Paris 2024 is a global event in the energy sector, bringing together industry leaders, engineers, researchers, and policymakers to discuss the latest advancements in high-voltage electricity transmission. InterOPERA project participated at CIGRE Paris 2024 and presented its approach to advancing multi-vendor HVDC (High Voltage Direct Current) grids, a critical component for the large-scale transition of the European energy sector. The presentations were held in two parts.
Objectives and Functional Framework
The first part of the InterOPERA presentation outlined the project’s objectives and general approach. It focused on creating a functional framework that facilitates interoperability by design, particularly emphasizing grid-forming capabilities for both offshore and onshore converters. This framework includes developing connection requirements for different subsystems at their DC Point of Connection. Additionally, the session will explore grid-forming functionalities in the context of multi-terminal, multi-vendor HVDC systems for wind power integration, with some concepts being demonstrated in a real-world setting.
Multi-Vendor HVDC Projects – Processes and Testing
The second part will delved into the processes and responsibilities involved in multi-vendor HVDC projects. As these projects represent a significant shift, subsystem compliance with functional specifications must be thoroughly verified through stand-alone tests, followed by system integration and de-risking via interaction studies. InterOPERA’s approach includes using offline simulations and a real-time physical demonstrator to validate the processes. The session will also cover the legal and contractual aspects essential for successful multi-vendor collaboration, including confidentiality and quality assurance.
