Dear Creators and Users of Matpower,

I have a problem with Unit Commiment problem. I've studied all examples 
attached to Matpower and also I've created some more cases before going to my 
large problem. It seemed to give me correct results. I'm using Gurobi.

Now I'm trying to run 118 bus case with 13 additional wind farms. What I have 
observed is, that MATPOWER is sticking to the first plan of work (no startups 
or shutdowns though cost of it is 0). What is more is some cases it is 
impossible for MATPOWER to calculate long period e.i nt = 24. I have written 
simple script to cut this long period into 4 6-hour periods. Then Matpower was 
able to calculate each of them. Plot_UC of each 6-hour period is attached.

Do you have an idea what could be problem? 



nt = 6;
mpc = loadcase('MMcase118v5');
Pg = mpc.gen(:,PG);

for i = 1:4
 result = MM_118bus_UC(nt,Xwind,Xload,cw,cl,Pg);
 if result.results.f>0
 res(j) = result;
 Pg = result.results.Pc([1:19],nt);
 cw = cw+nt;
 cl = cl+nt;
 j= j+1;
 else
 break
 end
end
