I am trying to solve a non-convex economic dispatch problem for a set of power plants that have a quadratic function in the objective function.  

I keep getting the error below when I run the model:

*** Quadratic equality constraints are non-convex. Set NonConvex parameter to 2 to solve model.
*** Activate nonconvex bilinear solver with Gurobi option nonConvex=2.

How can I activate the Gurobi option nonConvex=2 in GAMS?

  Hi,

  You have to set the nonconvex setting to 2 as described in the GAMS documentation on Solver Options File Usage.

  Best regards,
