This SUC intends to describe the process describing the coordination between the TSO and the DSO to solve congestion constraints in the transmission network. <br/>Three situations can be considered: <br/>1 a) TSO informs to the DSO some power limits at the substations for its work planning: The TSO can ask in operational planning to the DSO to limit the power consumption/injection of the substations that will be concerned by its work planning. To do so, the DSO may need to make a network configuration which can involve operation in loop for a short period. <br/>1 b) TSO informs to the DSO some power limits at the substations for the security system in case of incident in the TSO network. The TSO can request, in real time, the DSO to limit the power consumption/injection at some substations. To do this, the DSO can proceed to a network configuration which may involve operation in loop for a short period. <br/>1 c) The TSO can anticipate in operational planning or verify in real-time some congestions in transmission network and coordinate with the DSO some actions to solve this congestions through the MV voltage network reconfiguration. <br/><br/>This SUC is much related with the SUC Distribution network reconfiguration because is the only lever available at the moment to assure this limit. In the future, other levers can be considered.<br/>
