It looks to me like there may be either some network congestion or some ramping 
restrictions that are causing the wind output to be curtailed. It’s hard to 
tell without having a full working script with all input files here to 
replicate what you are seeing. Can you try eliminating the branch flow limits 
(set RATE_A to 0 for all branches) and see if that resolves it? And 
double-check the values of load-following ramp reserves in the wind xGenData 
inputs.

If you are not able to resolve it with these hints, feel free to submit this as 
a question in the MOST issue tracker <https://github.com/MATPOWER/most/issues> 
and attach the files needed to reproduce the problem.
