Use Input Prices
With this box is checked, Aurora will dispatch resources to a specified price level, rather than to a demand level (from which prices are derived), which is the standard dispatch. The model uses input prices for the internal or pre-forecast of prices, which is the basis for commitment and storage scheduling decisions, for portfolio computations. It disregards the setting for Use Input Prices for Internal Forecast Only in Traditional Commitment.
After modifying commitment and storage scheduling decisions (based on input prices), Aurora performs a standard dispatch for all the zones running in the system. This will determine economic imports and exports, as well as the resulting net load and marginal resource reported for each zone in the study for each hour. When the study is complete, the model will overlay the input prices in the zones specified and dispatch the resources in the specified zone to the input prices.
This modified dispatch represents a supply-side adjustment only. There is no attempt to force adjustments to imports, exports, or net load to match the input price at this point. This setting requires you to select the Electricity Price table in the project file. If no table is selected, an error will be generated.
NOTE: If this option is NOT selected and the Use Input Prices for Internal Forecast Only option is used, then input prices will be used for the pre-forecast of prices only. This will cause commitment and storage scheduling decisions to be made against the input prices, but then the model will perform the standard dispatch for all the zones running in the system to determine final zonal prices reflecting those decisions. No overlaying of prices and re-dispatching will occur.
NOTE: This option cannot be used with Dynamic Price Commitment.
