The use of DLN combustion is becoming more common
due to stricter regulations. The additional constraints that it
brings regarding the operation of the power system must not
be underestimated. It is necessary to carry out in depth
studies and simulations of all possible operating modes of the
power system in order to be sure that the loads can be
supplied at the right frequency and voltage. This is especially
the case when there are turbines having different operation
modes (DLN and standard) at the same facility.
