Information

1. Purpose of model

Simple heuristic model for a unit commitment of generators. Based on the load prediction (or actual load if no prediction is available) and the minimum and maximum power boundaries of the available generators the algorithm in this model commits or decommits the generators. Commitment means the generator is operating.

Since no maximum gradients are taken into account a safety factor is introduced which allows to commit more generators to be on the safe side (simple gain on the load prediction).

Furthermore, generators can be marked as must-run, if they are absolutely needed e.g. for control power or coupled heat generation.

2. Level of detail, physical effects considered, and physical insight

See 1.)

3. Limits of validity

There is no check at all that the produced unit commitment is able to cover the actual demand

4. Interfaces

Input: Load (prediction)

Output: Boolean for each generator (true = generator should be in operating mode)
