Demand charge and dispatch decisions
In the KB I’ve found this article which states that demand charges in HOMER do not impact the dispatch decisions during simulation.
However, if I define a very expensive peak demand charge for 6pm, for example, the genset is dispatched at peak hour (please find a print attached), which is great.
Is the article outdated?
The dispatch decision is independent of the demand rate as mentioned in the knowledge base article. The generator being dispatched could be because of multiple reasons depending on your system. It could happen if you set a demand limit above which the generator is dispatched as an act of peak shaving. If I can have a look at your HOMER file, I might be able to give you a clearer answer. Thank you.
