Special features#
Several special features can be included in the RAO optimisation:
limiting loop-flows on cross-zonal cnecs
monitoring (rather than optimising) the flow on certain FlowCnecs (MNECs)
not taking into account certain FlowCnecs - under specific conditions - for the computation of the minimum margin in the objective function
The objective function value is separated into two categories:
the functional cost reflects the business value of the objective (i.e. the cost associated to the minimum margin and the business penalties on usage of remedial actions)
the virtual cost reflects the violation of some special constraints. The first two special features (loop-flows & MNECs) are handled through the virtual cost.
