The use case defines information exchange between TSO and DSO in order to improve programming of their networks operation. DSO can forecast the load and distributed generation disaggregated by technology type (wind, PV, hydro, CHP, etc.) and location, which may be done with up to 15 minutes sampling period. Once exchanged with the TSO, in a properly aggregated manner, this information will allow having a more efficient and secure operation of the bulk power system.<br/><br/>There are cases in which the distribution grid is operated with connections between two or more TSO substations, creating network loops through distribution level. In this sense, a common observability area for both system operators needs to be defined, including visibility of the TSO over possible distribution network loops. If TSO considers in operational planning stage the foreseen network topology of the DSO, the security assessment (N-1) of the power system can be significantly improved with associated benefits to both TSO and DSO.<br/><br/>On other side, DSO also needs to accurately estimate power flows on its own grid, which may be affected by different configurations of transmission network topology. Therefore, the foreseen connection state of specific transmission lines, connecting more than one TSO substations and with significant impact on distribution network power flows, can be exchanged with the DSO for operation planning purposes.<br/><br/>In the above mentioned scenarios, the exchange of operational planning data, such as foreseen connection state, maintenance actions and electrical characteristics of specific lines must be exchanged between TSO and DSO.<br/><br/>In this use case, operational planning data exchange is done 72 hours ahead, being refreshed every 24 hours, using state of the art, standardized technological means.<br/>
