Cogeneration for Dummies

Hi, Antti,

Thank you for your reply; it's obviously working as expected now.

The CHPR (0.67) parameter is the result of 0.30 thermal efficiency divided by 0.45 electrical, given in the example of the Veda manual (I told you I was just playing with cogeneration). Most of the real backpressure data I have is greater than that.

I understand why it's better, if expressing heat in tonnes, to then model efficiency in terms of electrical efficiency only. Can you please help me with changing NCAP_CHPR accordingly? Do I have to use a coefficient to transform thousand tonnes to PJ to be able to compare them?

With respect to the COM_LIM parameter: In VEDA there are dummy processes that if the solution of the model is correct should be empty. But if you model without using VEDA, they don't exist. So, I am thinking of introducing the dummy processes in my model, maybe one import and one export, that produces/consumes all resources/commodities, and input them a very high cost. Do I have to use the parameter COM_LIM FX for every commodity, so that if there's any wasted commodity they appear in those dummy processes, and in that way check for errors in the model? Or with the very high cost only is enough?

Thank you again,

Sara
