Projects are expected to address all the following items:
- Develop new and improved knowledge and insights into the synthetic inertia, frequency control, very fast voltage support, and overall support to the system stability offered by grid-forming inverters (GFIs). Develop and/or update relevant models and simulation tools;
- Develop and demonstrate innovative grid control and grid-forming solutions that leverage the capabilities of GFIs with the view to enable mass deployment of GFIs;
- Address use cases for both transmission- and distribution-level grids, ranging from applications used in residential and commercial domains up to the use in large RES generators (PV or wind) and grid-scale battery storage systems. They could also consider solutions that include LVDC microgrids that are connected to the main AC grids;
- Take a system-wise approach, including control strategies that can effectively encompass wider areas;
- Develop interoperability between different solutions and products from different GFI manufacturers. Devise standardised approaches through the use of hardware in the loop and advanced simulation models for GFIs;
- Leverage modern solutions, including digital twins and artificial intelligence. Use and/or develop, to the greatest extent possible, open-source software solutions and or software modules.
- Develop a manual and propose best practices on this matter to be used by TSOs and DSOs. Propose sets of standardised technical requirements for GFIs, test models and procedures for verification of compliance (for the use of TSOs and DSOs) Identify remaining gaps and further needs for research and development. Suggest market conditions and/or opportunities that would incentivise the deployment at scale of GFIs.
