π€ AI Summary
The European energy systemβs transition toward renewable integration, digitalization, and distributed architectures necessitates enhanced cross-component and cross-system interoperability; however, a structured, comprehensive understanding of current interoperability testing capabilities across Europe remains absent.
Method: This study conducts the first systematic survey of 30 European smart grid test facilities, employing a structured questionnaire and multidimensional comparative analysis, integrated with established standards, reference use-case libraries, and evaluation models to develop a taxonomy covering test environments, methodologies, and standardized use cases.
Contribution/Results: The work delivers (i) the first pan-European interoperability test facility landscape map; (ii) a unified interoperability testing framework with an evolutionary roadmap; and (iii) publicly released classification criteria and infrastructure development guidelines. By addressing a critical systemic gap, this research enables transnational collaborative testing ecosystems and informs strategic decision-making for integrated, interoperable energy infrastructure.
π Abstract
The ongoing transformation of the European energy landscape, driven by the integration of renewable energy sources, digital technologies, and decentralized systems, requires a high degree of interoperability across diverse components and systems. Ensuring that these elements can exchange information and operate together reliably is essential for achieving a secure, flexible, and efficient energy supply infrastructure. While several initiatives have contributed to the development of smart grid testing infrastructures, they do not provide a dedicated or comprehensive focus on interoperability testing. A structured and harmonized overview of interoperability testing capabilities across Europe is therefore still missing. This work therefore presents a novel contribution by analyzing the European interoperability testing facility landscape through a structured survey of 30 facilities. It provides a categorized inventory of testing infrastructures, applied methodologies, and reference test cases, and introduces a blueprint for the development of future testing environments. The findings contribute to the establishment of a coordinated European ecosystem for interoperability testing, supporting collaboration, innovation, and alignment with the goals of the energy transition.
