Transmission-Distribution Interoperability Mechanisms (TDIM)

The various existing and expanding number of emerging functions and protocols that need to be executed across the Transmission-Distribution Interface (TDI) in their formalised and automated form. Key areas of priority are expected to include enhanced, low latency data exchange relevant to Frequency control, Voltage control, Congestion management Energy flow, Power-based services and System Balancing.

Underpinned by appropriate decisions about the enabling Cyber-physical Architecture, the TDIM will play a key role in supporting next generation Visibility, Operational Coordination and Resource Adequacy analysis.

Given the fast-evolving nature of power system transformation, the Future Grid Accelerator (FGA) has the status of a perpetual BETA version. Your suggestions for how each concept and definition may be enhanced are very welcome.

All feedback will be reviewed and considered for inclusion in subsequent updates.
