What is the difference in results between the AC contingency Solution (ACCC) method and the N-R solution Governor Redispach method
in one method before the same contingency it gives me 59% overload and in the other it gives me 85%
In a normal solution (FNSL, ACCC, etc.) the swing bus takes up the MW mismatch. Normally you have only one swing, so the whole MW error will be compensated by one plant.
Solving with inertial/governor dispatch (INLF) means that the power taken up by the swing will be redistributed to all generators according the their MVA size (MBASE). This will of course lead to a different load flow in the network.
Solving with INLF (Governor response) is a way to study the effect of primary frequency control without performing a dynamic simulation.
thanks, What you say is correct, However in the PSSE 33.5, it gives you the option to do the simulation with a governor response, defining a dispatch subsystem, where it is supposed to distribute the mismatch in all the machines of that without their subsystem the answers always differs
