Dear Matpowers, Hope you are doing great. We are trying to run PF for a distribution network in Matpower. Since the R/X ratio is acceptable we tried NR. It did converge, however, the loss is not correct. We think we have a difficulty on how to include substation into the code. We modeled it as a huge generator but it did not work. Since Matpower has been designed for transmission systems and there is no substation in the original model we were wondering if you could give us some hints with regard to the way we may consider the first bus as substation.
Best regards, Haneen Aburub
