I am currently facing the problem of gurobi does not support signomial constraints.

 

These are the line of codes that cause this issue.

const=[const, interp1(FC.PowerData, FC.hcData, FC.P, 'milp')<=FC.hc <= (1200/sum(FC.Pflag.*repmat(scenario.duration,nFc,1)))];

 

 

 

I got the code to work before adding "FC.Pflag.*" into the constraint, and the FC.Pflag is declared as 22x1 binvar as a design variable.

I read that this can be modeled to solve this issue but I do not know how to do so. 

Would appreciate the help and assistance for this! Thank you in advance!

  Gurobi does not support trigonometric functions directly. You can use Gurobi's piecewise-linear approximation feature to approximate \(\sin\) and \(\cos\) functions. You can use this feature via the genconcos and genconsin fields in the Gurobi MATLAB model argument.
