GAMS vs Matlab vs Modelica

Postby Lenilein78 » 5 months ago

Dear All,

I'm in the process of choosing a modeling environment for my research project and would be extremly thankful to hear your experienced opinions on following:
my task is to perform global optimizations (probably based on MINLP) on industrial energy systems including electricity/heat storage options and renewable energy modules.

After some research on the different available tools my thoughts are followings:
- Modelica and Matlab provide really good model librarys: for example Modelica offers the libraries TechThermo for energy storage systems, WindPowerPlants for Wind Turbines, ElectricalEnergyStorage, PhotoVoltaics etc.
- the current most powerful optimization tools are available under GAMS modeling language (solvers CPLEX, Baron for example);

As optimization is going to be a core process in my project (and we already have a license for in my Research Institute), my preference is to use GAMS. However, I found very few models in the GAMS Model Library that could help me for my work and they seem to deal with entire systems (like for example Simultaneous Optimization for Hen Synthesis).
Do you know if there are models available for energy system components like for example a model for CHP, solar collectors or heat/electricity storage technologies? And where I could find such models?


Thanks!
Hélène

Hi,

here are two simple power models (but that are probably the ones you found already):

https://www.gams.com/latest/gamslib_ml/ ... rkpow.html

There is also a (very simple) CHP model packed into an Excel application:

Maybe this book will be interesting for you:

Best regards,

Great, thank you very much Lutz!
From what I see online, the book that you recommend has not yet been released...however I'm sure it will be of great help once it is!
