Automatic SFT constraint generation in EMO
The aim of automatic SFT constraint modelling in EMO is to model the SFT constraints that are generated as part of the dispatch and pricing solution in SPD. These constraints are designed to avoid thermal overloading of a line in the event of the unexpected outage of any other line. SFT constraints appear in the dispatch and pricing optimisation model as linear constraints between two lines. For example:
-0.902*OHK_WRK.1+1.274*THI_WKM1.1 <= 605.79
In this case THI_WKM1.1 is the line being protected from overload and OHK_WRK.1 is the line which may cause overload in THI_WKM1.1 if it has an outage. The general form of the SFT constraint is
Equation 1. \(A F_{M} + B F_{C} \leq C\)
