I am interested in CPF using MATPOWER with load increment at multiple buses.Can you please send me the MATPOWER code that runs for multiple bus load increment for CPF? Thanks Shrikant

That is not how transmission networks are designed. Shri wrote: > Hi, > I am trying to create a bigger test case by duplicating a MatPower test >case (>= 2383 buses) multiple times.
