Hi all,
We were recently asked how to add a new offer to vSPD for testing purposes. To be clear, this question pertains to the standalone version of vSPD, and not vSPD-online.
Currently, we can easily modify the existing offer in vSPD but it is not straightforward to add a new (undeclared) offer into vSPD. In this topic, I will present some sample code that can be used to add a new offer ("ABC2201 XYZ0" ) to an existing location/pnode (e.g. HAM2201). I would recomend that this code snippet be inserted between code sections 4 and 5 of the vSPDSolve.gms file as follows:
*=====================================================================================
* 4. Input data overrides - declare and apply (include vSPDoverrides.gms)
*=====================================================================================
$ontext
- At this point, vSPDoverrides.gms is included into vSPDsolve.gms if an override file defined by the $setglobal vSPDinputOvrdData in vSPDSetting.inc exists.
- All override data symbols have the characters 'Ovrd' appended to the original symbol name. After declaring the override symbols, the override data is installed and the original symbols are overwritten.
- Note that the Excel interface permits a limited number of input data symbols to be overridden. The EMI interface will create a GDX file of override values for all data inputs to be overridden. If operating in standalone mode, overrides can be installed by any means the user prefers - GDX file, $include file, hard-coding, etc. But it probably makes sense to mimic the GDX file as used by EMI.
$offtext
$if exist "%ovrdPath%%vSPDinputOvrdData%.gdx" $include vSPDoverrides.gms
*--------- adding a new generation offer ---------------------------------------------
$onmulti
*1. Declare a new offer (Ex: "ABC2201 XYZ0")
set i_Offer 'Adding generation offer' / 'ABC2201 XYZ0' / ;
$offmulti
*2. Map the new offer to an existing pnode (Ex: "HAM2201")
i_tradePeriodOfferNode(tp, 'ABC2201 XYZ0', 'HAM2201') = yes ;
*3. Map the new offer to an existing trader (Ex: "38486") . You can use any trader in the i_trader list
i_tradePeriodOfferTrader(tp,'ABC2201 XYZ0','38486') = yes ;
*4. Adding offer paremeter data
i_tradePeriodOfferParameter(tp,'ABC2201 XYZ0','i_initialMW') = 0;
i_tradePeriodOfferParameter(tp,'ABC2201 XYZ0','i_reserveGenerationMaximum') = 10000;
i_tradePeriodOfferParameter(tp,'ABC2201 XYZ0','i_windOffer') = 0;
i_tradePeriodOfferParameter(tp,'ABC2201 XYZ0','i_FKbandMW') = 0;
i_tradePeriodOfferParameter(tp,'ABC2201 XYZ0','i_rampUpRate') = 9999;
i_tradePeriodOfferParameter(tp,'ABC2201 XYZ0','i_rampDnRate') = 9999;
i_tradePeriodRiskGenerator(tp,'ABC2201 XYZ0') = no ;
*5. Adding offer quantity and price
i_tradePeriodEnergyOffer(tp,'ABC2201 XYZ0','t1','i_generationMWoffer') = 100 ;
i_tradePeriodEnergyOffer(tp,'ABC2201 XYZ0','t1','i_generationMWofferPrice') = 0.01;
i_tradePeriodEnergyOffer(tp,'ABC2201 XYZ0','t2','i_generationMWoffer') = 100 ;
i_tradePeriodEnergyOffer(tp,'ABC2201 XYZ0','t2','i_generationMWofferPrice') = 1000;
*=====================================================================================
* 5. Initialise constraint violation penalties (CVPs)

Hope this helps,
