RTE develops its own DLR system including the congestion management

tools and risk mitigation without any sensor on the cables

Congestion management

• Today :

−maintaining all the interconnections inside the perimeter ishighly risky by windy days (N-1 probability high and loadtransfer on 90 kV needs a fast response in a time notcompatible with scada abilities)−Clustering the area is the only solution to avoid the risk and

guarantee the security for electrical risk -> weakened gridresilience (N-1 not guaranteed, shutdown for the cluster,consumers and producers are impacted)

• Tomorrow :

−Local tools for fast response : acceptable durationestimation, load flow for topology optimisation, «surgical »load shedding plan activation and emergency shutdowntools, potentially storage management (not market oriented)−Interconnections maintained all the time, no need to

anticipate de N-1, the system does it in real time

Poste Intelligent Conclusion

• A project dedicated to global enhanced performances(reliability, maintainability, fault tolerance, self healing,OPEX and CAPEX, sustainability,…)

• Delivering extended capacities for RES integration
