Please read the first post of [Please read: make it easier to help you](https://discourse.julialang.org/t/psa-make-it-easier-to-help-you/14757). In particular, it’s easier to help if you can provide a minimal working example. You’re almost there, but I can’t run your code because I don’t have “warmstart.jl”.

One reason you are having trouble is that you are enforcing variable bounds as constraints. Do this instead:

```nohighlight
@variable(m, Pgmin[i] <= g[1:times, i = 1:numgenerators] <= Pgmax[i])

```
