EMarket is capable of modelling the Reserves market and co-optimising it with the wholesale electricity market.
To use Reserve Modelling, this option needs to be set in the Dispatch Mode field in the Run Window.
Note: Reserve modelling is significantly more complex than standard nodal modelling, requiring additional run time. It is recommended Reserves modelling is disabled at run time unless you specifically need to produce Reserves data or wish to investigate the interaction of the Reserves and Energy Markets in some detail.
The Reserve Window is used to specify:
- Reserves-related detail to assist EMarket precisely dispatch Reserves
- Interruptible Load Reserves details by user-defined Region
The 'Reserve Window has the following components:
- Details Box (Name and Description)
- The Regional Reserves box
- The Interruptible load Reserves box
Regional Reserves Box
| Region | The Reserve Offer Region. Note: For the correct operation of the Reserves model at run time all Reserve Regions specified in the Reserves Resource must have corresponding Reserve Regions in the Grid associated with the Run Definition. |
| RefNode | Reference Node for the Reserve Region. |
| Base Risk (MW) | The amount of base risk for the region (modeled Reserve risk never falls lower than this value at any time). |
| Import Risk Subtractor (MW) | This relates to the risk set by lines that are used to import energy into a Region. E.g. a line with a 500 MW capacity imports energy and, for a particular Run Tick, the line flow is 200 MW - if the Import Risk Subtractor setting is 150 (MW), then the risk set by the line is 50 MW (200 MW - 150 MW). |
| RAF FR | The Fast Reserve adjustment factor. |
| RAF SR | The Slow Reserve adjustment factor. |
Interruptible Load Reserves Box
This is used to enter Fast and Slow ILR Offers by region. ILR Offers can be entered as fixed values or made time dependent using the Array Table and Timeseries Functions.
ILR Box Fields
| Type | The type of Reserve the ILR Offer applies to - Fast or Slow. |
| Region | The Reserve Region the ILR Offer applies to. |
| Offer Name The name (including band number) of the Offer as it will appear in the Dispatch_FR or Dispatch_SR results. | |
| Quantity (MW) | The Quantity of Reserve offered. This field can be made time-dependent using a formula |
| Price ($/MWh) | The Price of the Quantity offered in $/MWh |
Warning: The ILR Regions must match the Regions specified in the (Reserve) Regions field within the Grid Nodes Box of the Grid Window.
