This use case defines information exchanges between TSO, DSO, Flexibility Operators and Market Operator necessary for procurement of flexibility provided by distributed energy resources. <br/>Flexibility Operator interacts both with TSO and DSO and it is necessary to validate coordination mechanism that will prevent double activation of the same service at the same time. TSO and DSO should also collaborate in order to avoid negative impact of DFR (Distributed Flexibility Resource) activation on their respective networks.<br/>Three main scenarios should be considered:<br/><ol>
<li>The Flexibility Operator provides services for the TSO (national flexibility market) and the DSO should validate, in day-ahead or intraday timeframes, the activation of these flexibilities (for the resources connected in distribution network)</li><li>The Flexibility Operator provides services for the DSO (local flexibility market). The DSO should provide, in day-ahead, the forecast load/generation for each primary substation including the activation of the procured flexibilities. The TSO should take into account this information for the balancing and congestion detection proposes.</li><li>The Flexibility Operator connected to distribution network provides services for the both for TSO and DSO in a coordinated local and national market mechanism. The offers not accepted in the local market are sent to the national market. At national market the TSO can obtain flexibilities from the Flexibility Operators connected on transmission and distribution networks.</li><li>The Flexibility Operator provides services for the both for TSO and DSO in a single procurement platform (single market). The activation of the offers should be agreed both by TSO and DSO.</li></ol><p/>
