Files in this directory
=======================

This directory contains the files used in the vSPD analysis.

The vSPD analysis has two purposes:
- To produce the scenario (which is used for all charges)
- To produce counterfactuals (which are only used for the SPD charging method).

Subdirectories include:
- Inputs - GDX files which are the inputs of vSPD
- Programs - the vSPD code (which has been modified for the purposes of this project)
- Output - a blank directory where any new vSPD results should appear
- Stored_outputs - the nodal results that have already been output by vSPD, in CSV format

These nodal results, in turn, are converted to a SQL table - which is stored in the '..\Scenario_as_an_SQL_table\' directory.
 This is the form in which they are used in the calculation of charges.

Model runs
==========

There are seven model runs.

The first is the base case, which is the modelling scenario, and is used for all charges. It uses a VoLL of $3,000/MWh.
 It is also the factual, in the SPD charging method, for all the investments except Pole 2 and OTB-HAY.

The remaining six are used in the SPD charging method only. They are:
- Base case, with VoLL=1000  [The factual for Pole 2 and OTB-HAY]
- Monopole                   [The counterfactual for Pole 3]
- noHVDC, with VoLL=3000     [Not used]
- noHVDC, with VoLL=1000     [The counterfactual for Pole 2 and OTB-HAY] 
- noBPEHAY                   [The counterfactual for BPE-HAY]
- noWRK                      [The counterfactual for Wairakei Ring]

While there are seven sets of CSV output files, there are only five sets of GDX input files.
This is because the choice between VoLL=1000 and VoLL=3000 is controlled by the VoLL parameter within the vSPDsolve.gms file.

To run vSPD
===========

- Extract desired .GDX input files into /Inputs
- Open /Programs/vSPDRunFile.xls
- Populate the "Settings" sheet, including the path to the GAMS directory.
- Specify the .GDX files to include in the "InputFiles" sheet of the spreadsheet.
  -The spreadsheet "Input_File_Creator.xls" found in /Programs may assist with this
- Press "Run vSPD" in the "MainMenu" sheet
- The CSV output files will appear in /Output.
