Re: load reduction in continuation power flow (CPF)

The code looks correct to me. I’m not sure why the load margin decreases, but the changes in load (from positive to equally negative) may be forcing the OPF solution into generator dispatch solutions that somehow reduce the load margin. Ray > On Feb 15, 2017, at 10:45 PM, Majid Mehdizadeh

I don’t have the case file you are using so I can’t run your example. Also, I don’t have time to debug your code. If you can reduce it to a single call to runmarket() that is not behaving as you expect, I’m happy to attempt to clear up any questions you may have. Ray > On Feb 16, 2017,

I agree with Ray. The base case dispatch being updated by OPF causes a reduction in generation, commensurate to the load reduction, and hence you are seeing a decrease in the load margin. What happens when you decrease the load at some other buses? Do you get the same behavior? Shri From: Ray

I have tried the same load reduction in other ieee cases and again i have got the same answer. It is a big question in matpower cpf function that when the load of system reduces, why the load margin becomes lower? May be we should use a same target loading and generation in every cases. It means
