Hello everybody,

I have a MINLP problem (BONMIN solver). This problem have some variables (P_size(j), P(j,t)...)

This is the objective function

Code: Select all

```
eqOpt1.. total_cost =e= sum(j,w_C(j)*SBASE*P_size(j));
```

and this equation as constraint (and others of electrical problem)

So in my solution P_size(j) is calculate good, but P(j,t) not choose the minimum value (that is I want), GAMS provide a solution close to the maximum value P_size(j)~P(j,t). How can i do it? I am always interested in having the smallest value of P

Thank you so much
