Dear Dr Zimmerman,
A simple ACOPF objective function is : minimize Pgen * fuel_cost , where
fuel_Cost is $/MWh and Pgen the MWh produced.In MatPower, I set the fuel costs
for Pgen, in the mpc.gencost matrix. I do not set any costs for Qgen
production.
I also set in the mpc.gen matrix, that Qmax=100 and Pmax=100 and also I set
rateA=10000 i.e. no line constraints. Also, bus voltages are within statutory
limits.
Matpower results state than generator 1 produces 0 MVAr, generator2 produces 50
MVAr and generator3produces 60 MVAr, at certain voltages.
How does MatPower select these values for Qgen and Voltages, given that there
is no objective function governing them? The only constraint is Qgen <=100,
and V within limits.
Thank you,Giannikos Stas
