Hello,
I have been working on an assignment and I can not figure out what the problem
is. I checked my system and readings several times but still my system isn't
converging. Any help will be appreciated.
%%- Power Flow Data -%%
%% system MVA base
mpc.baseMVA = 100;
%% bus data
I have saved as case9 file with the new name case92.
I am using this code to decrease my line flow of 4-5. For that I need to
decrease the generation 3, but it's not decreasing with this code.
Please help me.
mpc= loadcase (case92)
[MVAbase, bus, gen, branch, success, et]=runpf (case92)
a=branch(
Pass the casestruct 'mpc' instead of the filename 'case92' to runpf
runpf(mpc);
What problem are you trying to solve by decreasing the line flow? Maybe we
could suggest a better for what you are trying to do.

You sent the data but forgot to mention what analysis are you trying to do? Are
you running a power flow or an optimal power flow? If a power flow, then are
you using Newton Method (default), fast decoupled, DC? If OPF, then DC or AC?

I am working on a fuzzy logic program which reduces the tie-line power flow
and frequency deviation. I have made line 4-5 a tie-line.
What I'm trying to do right now is, I'm decreasing the load on bus 5
manually, and then I want to decrease the generation of gen-3 by for loop.
I did find my that
I want to run Newton Raphson or Gauss Seidal power flow.

The generator voltage magnitude setpoints are not set n the data. This should
be set in mpc.gen(:,6).

Dear Dr. Zimmerman,
I may be wrong, but apprently, in opf_costfnc.m, line 135, there is an
issue which it not clear to me. In calculating the gradiant of cost
function, baseMVA is multiplied as in:
df_dPgQg(ipol) = baseMVA * polycost(gencost(ipol, :), xx(ipol), 1);
However, in calculating xx(ipol
Some of your branch impedances are way too small; you should probably collapse
such electically similar buses into a single bus.
