[Bldg-sim] Dynamic demand

[David Bradley]

Chris,
Two things come to mind. We've done something similar in simulating 
grid-tied power systems that include some renewable sources (wind and 
pv), a battery bank, an electrolyzer, a fuel cell, and a grid that is 
sometimes unavailable. The controls sense (among other things) the 
availability of the grid and act accordingly. I am also aware of some 
work being done at Penn State on a pv/battery system that knows what the 
utility rates are at the current time. Again the controls make a 
decision about whether to meet the load with the PV or with the grid 
based on something that is going on in the grid at the current time. 
Both projects were done using TRNSYS.
Kind regards,
David
