Notes: Real-time supervision and control of the power system is fundamental to ensure a secure operation of the grid in different voltage levels. Particularly, when it comes to the interface between transmission and distribution networks, the exchange of real-time information among neighbouring system operators is a very relevant aspect.<br/><br/>Proper real-time data exchange between TSO and DSO allows higher levels of system coordination and greater awareness on the state of operation of neighbouring networks. For that purpose, the exchange of real-time data between TSO and DSO is often put in place by means of Inter-control Center Communication Protocol (ICCP) allowing the communication between TSO and DSO SCADAs. <br/><br/>Defining appropriate observability areas of TSO and DSO is key to improve power system real-time supervision and control through better coordination. Enlarging real-time data exchange between TSO and DSO, expanding as well their respective observability areas, are the major objectives of this use-case. The use-case focus is on the following aspects:<br/><ul>
<li>Assessing real-time visibility of TSO and DSO on each other networks, expanding their respective observability areas when agreed </li><li>Enlarging real-time data exchange between TSO and DSO: <ul>
<li>Exchange of a comprehensive set of RMS measurements (P, Q, U, I) of transmission and distribution bays (transformers, lines, capacitors, reactors, …) within the agreed area of observability </li><li>Exchange of connecting state information of circuit breakers at transmission and distribution bays (transformers, lines, capacitors, reactors, …) within the agreed area of observability </li><li>Exchange of tap information of transformers, capacitors and reactors at TSO-DSO interface </li><li>Exchange of equivalent short-circuit power at TSO-DSO interface, distinguish between contribution of distribution and transmission connected resources </li><li>Other relevant data for TSO-DSO real-time exchange </li><li>Standardize real-time information exchange between TSO and DSO to ensure adequate understanding of data models and formats </li><li>Putting in place adequate procedures to ensure a regular review of observability areas of both TSO and DSO to accommodate additional visibility needs in face of any network modifications (e.g. topology and new connected grid users) </li></ul>

Notes: Exchange of real-time information between TSO and DSO concerning their own networks and other connected resources (SGUs) under normal network operation conditions. <br/><br/>In this use-case, the scope of real-time data exchange is limited to a predefined observability area of the TSO over the distribution network, as well as to a predefined observability area of the DSO over the transmission network.<br/>
