1.4. Narrative of Use Case

Short description

Real time congestion detection and management

Complete description

GRIDFLEX must periodically execute power flow calculations taking into account RT monitoring data in order to detect congestions (e.g. voltage violations, line power limitations, etc.) in the grid.

  • Input: RT measurements + state estimation results
  • Output: U/Imax issues GRIDFLEX must provide the grid operator with a list of actions to perform in order to mitigate the detected congestion.
