A Review of Interoperability Challenges and Solutions Towards a Digital Twin of the European Electricity Grid

A significant challenge for the European energy system decarbonization transition and climate neutrality is the cost-competitiveness of the renewable sources as well as the optimal system integration of these distributed renewable assets in a cost-effective way, particularly making sure that renewables will best adapt to grid connection regulations and operational constraints. In the smart grids’ operation, there are real-time data exchanges, interoperability and Open Application Programmable Interfaces as critical technology building blocks to enable plug and play data interfaces from DERs located into prosumer houses into energy markets federated through Flexibility Service providers, Market Operators as well as TSOs and DSOs. This information will enable the development of European digital twin of the electricity grids, which is the scope of the European project TwinEU. This work's goal is to present the results of a desktop analysis through the European projects to identify challenges and gaps in data interoperability and interfaces for the electricity grid operation. The analysis is carried out during the TwinEU project
