I am facing problem in DCOPF. I need help. In my power grid model i
have fixed the capacity of transmission line in RATE A column by 110% of
initial power flow. Then increase the load by a factor (1.01) and run the
dcopf. But matpower showing infeasible model due to which it is not converging.
I am not able to understand the problem. Here load and generation is also well
balanced. Now which parameter constraint to converging of my test case. I stuck
here for a long time, so please help me
The result shown below is after increasing the load by 1.01.

Subject: Re: load2disp command
Did you check the help for the function (e.g.
in the online function reference)?
idx is simply a vector of bus indexes, in your case it should be simply be
equal to 2 (a 1 x 1 vector).

I am using load2disp command and I understand everything in that command except
the input index.
Suppose I want to convert the fixed load to dispatchable load at bus 2 only.
I tried by using the following command-
It is not working?
Thanks in advance
