Notes: Several situations can be considered:<br/><br/>1. TSO informs to the DSO some power limits at the substations <br/>In this case, two options are possible :<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<br/>In case of incident in the TSO network, the TSO can ask in real time to 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/><br/>2. DSO proceed to a network configuration <br/>2 a) DSO proceed to a network configuration for its work planning needs<br/>As for the TSO work planning needs, the DSO may need a network configuration which can involve operation in loop for a short period. The DSO can evaluate the work planning in operational and real time.<br/>2 b) DSO proceed to a network configuration for the system security<br/>If an incident occur in the DSO network, the DSO can proceed (at real time) to a network configuration to guarantee system security.<br/><br/><br/>For all these situations and to validate the MV network reconfiguration, the DSO needs to have some observability of the TSO network (both at operational or real time).<br/><br/>The process to validate the network MV reconfiguration is presented below:<br/>1. Collection of input data<br/>The DSO needs some input data (at operational or real time) of both the TSO and the DSO network to launch an algorithm to obtain the estimated power flows.<br/>2. Launch of the algorithm to obtain an estimation of the current transit<br/>If all the input data is available, the DSO can perform the calculation of the current transit <br/>3. Make a decision<br/>If the current transit estimated not lead to constraints in distribution network, the load transfer can be made. Otherwise, the DSO should postpone the load transfer or look for another solution<br/>

Notes: Validate the MV network reconfiguration considering the estimated power flows in distribution network during the short period when the network is operated in loop. To do this estimation, the DSO needs some observability (in operational or real time) of the TSO network.<br/>
