Hi Ray,
Thank you very much for quick reply.
I'm working on the unit commitment example presented in the MOST manual
(Example 6). This is the code i'm using:


   -
   - casefile = 'ex_case3b';
   - mpc = loadcase(casefile);
   - xgd = loadxgendata('ex_xgd_uc', mpc);
   - [iwind, mpc, xgd] = addwind('ex_wind_uc', mpc, xgd);
   - profiles = getprofiles('ex_wind_profile_d', iwind);
   - profiles = getprofiles('ex_load_profile', profiles);
   - nt = size(profiles(1).values, 1);       % number of periods
   - mpc_full = mpc;
   - xgd_full = xgd;
   - xgd.PositiveLoadFollowReserveQuantity(1) = 10;
   - xgd.NegativeLoadFollowReserveQuantity(1) = 10;
   - mpc.gen(1,RAMP_30)=10;
   - mpc.gen(1,RAMP_30)=10;
   - mpc.gen(1,RAMP_10)=10;
   - mpc.gen(1,RAMP_10)=10;
   - xgd.InitialPg(1)=100;
   - mdi = loadmd(mpc, nt, xgd, [], [], profiles);
   - mdo = most(mdi, mpopt);
   - if verbose
   -     ms = most_summary(mdo);
   - end

 I would expect the generation dispatch of the first unit at the first
period to be restricted to 110MW. However,  the results show that the
generation dispatch of the first unit at the first period is 200MW.

I don´t really understand the problem. What can I do?

Thank you very much,
Tatiana
