Enabling System Flexibility through enhanced TSO-DSO Coordination: Insights from Pilot Projects

The increasing penetration of renewable energy sources, distributed energy resources (DER), and the electrification of transport, heating, and industry are significantly transforming power system operation. Distribution networks are increasingly affected by bidirectional power flows, dynamic congestion, and voltage issues, challenging traditional grid planning and operational approaches. These developments highlight the growing importance of enhanced coordination between Transmission System Operators (TSOs) and Distribution System Operators (DSOs) to ensure system reliability, efficiency, and flexibility.
