If you are not modeling any particular inter-temporal constraints, simply write
a loop to run your cases. Something like …
T = 24;
mpc0 = loadcase(‘<mycase>’); % load base case
for t = 1:24
mpc = mpc0; % set case for time t to base case
% modify the base case for period t using scale_load() or apply_changes()
or whatever
mpc = scale_load(<load scale factor for period t>, mpc);
result = runopf(mpc);
% save result of interest to some variables or files
end
Hope this helps,
Ray
