Fraunhofer Institute for Energy Economics and Energy System Technology
The GRAVITON project aims to expand a highly parallel, GPU-accelerated solution method for electrical load flows so that decentralized control systems and dynamic topology changes in the distribution and transmission grid can be seamlessly mapped. These enhancements will significantly accelerate critical calculations for the future energy system and enable their integration into real-time sensitivity analyses.
Project highlights
- GPU-accelerated solution method
- Electrical load flow calculation
- Integration of decentralized units and transformers
- Dynamic network topology (switching states, network switching)
- Scalability in distribution and transmission networks
- Connection to pandapower as an open-source framework
Transfer
- Publication of the extended solution method as open source in pandapower GitHub
- Accompanying open access paper documenting the algorithms and benchmarks
- 1–2 webinars for practical demonstration of the workflow and to answer technical questions
- Involvement of distribution and transmission system operators as associated partners for validation under real grid conditions
- Development of concepts for possible follow-up activities, such as the integration of additional grid management and forecasting tools
Through close cooperation with grid operators and the publication of all components in open source, GRAVITON creates a robust foundation for the planning and operation of future decentralized energy systems.
