When running a power flow the voltage at swing and PV buses is controlled by the VG column of the corresponding generator in the gen matrix, not by the VM column in bus. Setting the corresponding mpc.gen(slack_gen_index, VG) to the desired value in your loop should accomplish what you are looking for.

I am a researcher from the Alternative Energy Laboratory (LAFAE) in COPPE/UFRJ, Brazil. We are working in the modelling of a Wind Farm using Matpower in Matlab and we are trying to compare field measures with the results from the program. For this we are using a "For Loop" and setting different levels of Active and Reactive Power in the PQ buses. To increase our precision we are trying to change the Swing Bus Voltage level inside the "For Loop" but we have not seen any changes. We are trying to set the parameters like the Power References but we do not know if we are setting something wrong. Below there is an image of part of the code. <image.png> My question is: Is it possible to change this voltage level inside the loop? The only way that we see any change is when we change the Base Voltage in the modelling file, but not in the Iterative Loop. Best regards, -- João Amaral
