Thank you for your previous reply. Sorry to trouble you again. There is a competition between gas and coal for electricity generation. I have defined capacities of gas generation stock with CAP_BND attribute (FX), so remaining ELC demand should be satisfied by coal ELC generation. However, gas ELC generation are all replaced by coal ELC generation in millstone years, although its stocks are defined in BY table. How to make a kind of ELC generation to increase as same as defined stocks previously?
Attached is my model. Any help will be appreciated again!
I cannot
see any inconsistency, but can make the following observations:
oYour model is infeasible, due to the demands exceeding
the available capacity in the base year.
oAccording to your input data (fuel costs, technology
costs, efficiencies), it is much more expensive to use your very low efficiency
CHP gas technology than to invest into the cheap new coal plants and use them
instead, and so the results are as expected.
oIf you nonetheless want to force the gas CHP capacity
to be utilized, you could change your AFA to AFA~FX. But I'd also suggest to
set CEH=0 and CHPR=1 to at least have a decent total efficiency for the CHP
(that would give you a reasonable level of 88%).
