This example applies the load prediction to a BESTEST model

Buildings.Controls.Predictors.Examples.BESTEST

Information

This example applies the load prediction to the heating load of BESTEST case 600. On the right hand side of the model is the load prediction. It is configured to compute a regression based on the outdoor temperature. The output of the load prediction is compared with the actual heating power. This comparison is done in the block preErr which outputs the prediction error, normalized by the roughly the maximum heating power.

The figure below shows the predicted and simulated heating power, and the normalized prediction error.
