Reasons behind the project
D-GITT (Detailed Grid Inner Topology Timeseries) is a chapter of OpenSynth (LF Energy) dedicated to power grid descriptive data, including both real and synthetic datasets and the tools to generate them.
The initiative was created to address a key limitation in power system research: the lack of accessible, high-quality and structured grid data for simulation, modelling and AI development. As power systems become increasingly complex and data-driven, researchers and developers require realistic datasets that reflect operational conditions while remaining shareable.
D-GITT aims to bridge this gap by enabling open, collaborative access to grid data and fostering an ecosystem where data can be reused, extended and combined across projects.
Project objectives
D-GITT serves as the “grid infrastructure description” chapter of OpenSynth – LF Energy, providing a structured framework to organise and access grid data. It supports the storage and dissemination of real “backbone” datasets alongside associated synthetic datasets, enabling a consistent foundation of research and development.
The project aims to define a clear typology of grid data based on their nature (e.g. electrical characteristics, asset-related information), sensitivity (IP, privacy, safety), applicability (from steady-state load flow to dynamic and EMT simulations), and reliability. In addition, D-GITT promotes the development and integration of tools that can generate or reconstruct synthetic data to complement existing datasets.
Following its initial setup in 2025, the initiative will be further expanded in 2026 with enhanced infrastructure and a community challenge on real grid datasets, fostering innovation and validating new approaches for data-driven power system applications.
