EQ_COMBALM for ELCHIG
#1
Dear all,

I have a doubt about the equivalent Price in VEDA for the power sector, that is, an analogy of the electricity Price.
Currently, we have considering the price of the power system as the marginal value (shadow price) of equation EQ_COMBAL for the commodity ELCHIG. Although we have defined a profile for the generation in the case of renewable energies, based on time slices, the results of price are the same for all the time slices. Do you have an idea of which could be the problem?
 This is an example of the results:

Furthermore, we have some doubts about the formation of this price and the physical meaning, do you have any technical document about the meaning of the price and the definition in time slices?
Any information will be very welcome.
Best regards,
Miriam

You need to have different technologies as the marginal producer in different timeslices to observe the price differential that you expect. You will get some more information if you look at electricity generation by process and by timeslice.

Thank you for the answer.
I had a look to the electricity generation by process and by timeslice. Although there are diferente technologies producing in any timeslice the prices are the same. We have previously defined the technologies with different AFA by timeslices, and so, the energy mix is different.

In the model, some technologies are producing in all the time slices, and the electricity production is defined as annual. Could be this definition the motivation of obteining the same prices in all time slices?


I would like to know with does it mean "marginal producer" in TIMES. I suppose that is the more expensive technology in the electricity mix in any time slice. Is that correct? Furthermore, I supppose of the electricity production for one producer is associated to their variable costs.

A nice brief definition of marginal producer, quite consistent with the TIMES equilibrium, is given in the Mises Wiki:
