Hello,
I'm simulating a Gas Turbine Cogeneration System and I'm trying to minimize the total cost of the cycle based on the approach proposed by (Valero, Antonio & Lozano, Miguel A. & Serra, Luis & Tsatsaronis, George & Pisa, Javier & Frangopoulos, Christos & von Spakovsky, Michael R., 1994. "CGAM problem: Definition and conventional solution," Energy, Elsevier, vol. 19(3), pages 279-286), the so-called CGAM model, and also presented in Modeling, Analysis and Optimization of Process and Energy Systems by F. Carl Knopf (Chapter 10: Gas Turbine Cogeneration System Economic Design Optimization and Heat Recovery Steam Generator Numerical Analysis (Pages: 243-271)). Instead of using VBA in Excel as proposed by Knopf I would like to use Aspen Plus. I'm considering the same decision variables as well as constraints for the problem without success. Does anyone have any helpful material about EO Optimization in Aspen Plus? It would required a custom function.
Thanks
