FARAO v2.1.1 has been recently released. FARAO v2.1.1 notably includes all the features which were planned in July’s milestone of our CASTOR’s roadmap , that is to say:

  • Optimisation of preventive PST and topological remedial actions
  • Two possible objective functions : min. margin positive or min. margin maximized
  • Branch monitored in one or both directions, with thresholds defined in MW, A or %Imax
  • Branch monitored in N and N-1 states
  • AC and DC computations (for load flow and sensitivity analyses)
  • Limitation of loop-flows in the RAO

With in addition another key feature: the consideration of MNEC (Monitored Network Element) in the optimisation. The CRAC importers have also been improved, with some new development enabling to efficiently read real data in the standard file formats used for the capacity calculation of CORE, with hundreds of contingencies and thousands of Cnec.

Moreover, before its release, the RAO has been tested on several timestamps of the CORE capacity calculation process. The results of the first remedial action optimisations are very satisfying, and allow to increase the room for power exchanges between CORE countries, while making sure that the loop-flows do not exceed a given threshold, and that the MNECs keep a positive margin.

Our efforts in designing and developing FARAO are still ongoing, and new features are yet to come in your favorite remedial action optimiser!
