Dear Matpower Community,
I’m working on power flow project and have used grid data from database. I
have modelled all line parameters (R X B) in p.u. system, also same for
transformers and kept generator output until it satisfies active and
reactive power demand. For renewable generation, I
I would suggest trying the following:
1. Use the solution of a fast decoupled power flow or an optimal power flow
(with line limits and voltage limits relaxed) as the initial guess for the
power flow.
2. Follow step 5 in http://www.pserc.cornell.edu/matpower/#pfconvergence
making CPF to
You can modify the test case so that the bounds are very tight on the variables
you would like to keep constant.
Cheers,

Thanks Sir, I will try that. By the way, I am wondering whether you know
how to add new varaibles z using direct specification method? Many thanks!
Best Regards!

Shruti is right, the value you obtain for lambda is valid for all the
network, since voltage collapse is a global phenomenon (in other words,
you'll see a nose point at the same value of lambda regardless of which bus
you choose to plot). Remember that lambda represents a fraction along the
Hi Matpower communities,
The default runopf change all the control inputs, such as active power and
terminal voltage of PV buses. Is it possible to only change the values of a
specific subsets of , for example, PV bus instead of all of it! Many Thanks!
Best Regards!
