Blending Model Template Requirements

In addition to the typical template described in the Model Template Requirements, MetrixIDR provides support for templates that include two sets of models. Normally this would be used to support an hour-ahead/day-ahead blending model approach. The resulting models are blended together using a set of blending weights managed in the Manage Weight Sets, Blending Tab section.

The required structure of a Blending Model Template project file is similar to a typical Template project file. The critical differences are described below.

Data Tables

Data tables should be defined as for a typical Project file (see specifications above).

Models

A template model and two sets of interval models are specified within the Project. This will include:

  1. One set of hour-ahead models.
  2. One set of day-ahead models.

Additionally, the following is required:

  • The hour-ahead models should be named according to the convention "LoadINT_HA", where INT will be the interval modeled.
  • The day-ahead models should be named according to the convention "LoadINT_DA", where INT will be the interval modeled.
  • All models need to be locked.

MStat Compare Object

Two MStat Compare objects must exist:

  1. Stats_HA. This references the hour-ahead models.
  2. Stats_DA. This references the day-ahead models.

Both MStat Comparisons must have the following statistics checked:

  • Adjusted R-squared.
  • Regression MAD.
  • Regression MAPE.
  • Regression Std. Error.

GroupForecast Object

Two GroupForecast objects must exist:

  1. Forecast_HA. This contains the hour-ahead models (and optional daily energy model).
  2. Forecast_DA. This contains the day-ahead models (and optional daily energy model).

Both Group Forecasts should be set to return Predicted values.

Reports

The following reports are required:

  1. FcstPred_DA. The FcstPred report contains the day-ahead GroupForecast results as adjusted with the AdjPred transform table.
  2. EstPred_DA. The EstPred report contains the individual model predicted values for each of the day-ahead models.
  3. EstResid_DA. The EstResid report contains the individual model residual values for each of the day-ahead models.
  4. FcstPred_HA. The FcstPred report contains the hour-ahead GroupForecast results as adjusted with the AdjPred transform table.
  5. EstPred_HA. The EstPred report contains the individual model predicted values for each of the hour-ahead models.EstResid_HA. The EstResid report contains the individual model residual values for each of the hour-ahead models.
