Does this PR already have an issue describing the problem?
No.
What kind of change does this PR introduce?
This PR aims to remove network results and limit violation detection in the fast DC SA, for branches that have been disabled on one side due to a contingency.
What is the current behavior?
Currently, if branches are disabled only on one side (for example, in the case of a contingency on a busbar section), the fast DC SA will compute network results and may detect limit violations on these branches.
This behavior differs from the slow DC SA, as the latter uses a listener to replace
ClosedBranchSide1/2DcFlowEquationTermwithEvaluableConstants.ZEROwhen one side of the line is disabled. As a result, branch results are set to 0 on both sides, and no limits are violated (although they are still analyzed).What is the new behavior (if this is a feature change)?
In fast DC SA, a customized filter is now applied before computing the network results or checking for limit violations. This filter is inspired by the work done in PR #1169.
A branch where one side is disabled by a contingency is considered disabled, meaning no computation or verification is performed on these branches. This differs from the slow DC SA (see the previous paragraph), where the filter simply checks whether the branches have been disabled on both sides by the contingency.
Does this PR introduce a breaking change or deprecate an API?
