Hi all matpower users! I have two questions:
1. In the bus matrix, the columns VM and VA are used both for the initial guess when solving the power flow, and to store the resulting voltages? 2. When solving a cpf, I get lam_max which corresponds to the nose point, i.e. maximum load/generation increase before "voltage collapse" happens. I can also find the power flow at the nose point just by running an ordinary power flow with flat start and conditions corresponding to the maximum load. However, I have tried to do the same thing for the lower part of the PV curve but failed to reproduce the solutions from the cpf. Basically I thought I could get the lower part of the PV curve by just solving a power flow using initial conditions which are close to the "unstable"/lower solutions from the cpf (instead of a flat start), but I get different solutions. Thanks, Elis
