Save changes and exit vSPDfileList.inc.Open the file called vSPDfileList.inc, found in the vSPD Programs directory, and enter the list of GDX files commensurate with the days for which you want to undertake price sensitivity analysis.this setting is mandatory to activate the price sensitivity functionality). leave string between quotes empty if no override is to be used)
give the model run a name - this is required) Using File | Open, open the file called vSPDsettings.inc, which can be found in the vSPD Programs directory and edit the three variables called runName, vSPDinputOvrdData, and opMode:.Using the GAMS IDE, open the vSPD project file, vSPD.gpr, found in the vSPD Programs directory - File | Project | Open Project.Copy the required GDX input files into the vSPD Input folder.The remainder of this post sets out the steps required to take advantage of the price sensitivity functionality. To be clear, while this functionality is only accessible when using standalone vSPD, vSPD-online can still be used to undertake price sensitivity analysis, albeit not quite so conveniently. When the new functionality is activated, it also results in a new output file being produced that conveniently collects the results into a single file ready for further processing, such as running through a plotting script. The new capability enables price sensitivity experiments to be configured without having to explicitly construct an override. With the release of v3.0.0 of vSPD back in September 2016, we added the capability to quickly and easily configure the model to undertake price sensitivity experiments. For example, see Wholesale price/demand sensitivity or More demand response analysis. Both the standalone and online versions of the vSPD model have previously been used to study the impact on wholesale prices of changes in demand.
