Veda2.0 Released!


transportation costs between regions
#1
Hello, in my model I have 14 regions and I am not sure what is the best way to program transportation cost of biomass fuel between each of them? It would be the most convenient if I could define some matrix for these costs just like for the trade links but I don't know if it is possible

Hi, could anyone help? I have some idea how to make it more compact but I don't know if it is going to work

Veda2.0 does not support parameter declarations in matrix format.

Share some input data with me and I will give you some ideas on how to set it up.

Hello, I am attaching my screenshot. This is how I am trying to model transportation cost of commodity BIOFWC to other regions. Maybe this "matrix" looks okay but looking at the results, I am not sure what "cost_ire" means or "cost_flax". Where could I see actual transportation costs? Is attribute ACT_COST wrong? Thanks

The VEDA online documentation says the following:

• Not supported:

 ◦ Trade parameter declarations in matrix form (~TRADE_Param)
 ◦ There will be a utility to migrate trade links and parameters to alternate formats

As that statement was made already about three years ago, by now I think this utility to migrate trade links and parameters to alternate formats must have been made available. And I would find it quite useful myself.

However, I am not sure where to look for this utility. Has anyone else found where to look for using it?  Is it integrated into VEDA2 or is it a some kind of a "standalone" Excel tool?

Hello, in the following screenshot I am showing how I am trying to do it, it seems it is working. However, I have a trouble figuring out what COST_IRE means looking at the results, it is evaluated at the shadow price but what is the use of it?. This is how I am trying to model transportation cost of commodity BIOFWC to other regions in the attachment. I am trying to see actual transportation costs in the results to verify that everything is all right, but I can't. Is attribute ACT_COST right for trade commodity?  transportation costs are supposed to be in EURO/GJ

> Is attribute ACT_COST right for trade commodity?

If you define the cost with ACT_COST, the resulting annual costs are reported in Cost_Act. It works fine for trade processes, but it is not commodity-specific.

COST_IRE is indeed the trade expenditure/revenue obtained from the marginal cost of the trade link (from the trade balance equation), and it thus gives the annual expenditure or revenue related to the commodity imported/exported through the IRE process. It is useful if you want to include the prices of the imports/exports in the regional costs, otherwise they will not be reflected in the total regional costs.

Perfect, thank you very much, I was wrongly looking at the commodity to see the transportation cost. I looked at the trade process now and it is all correct. Therefore, I can also confirm that my "matrix" works
