Optimisation at times exceeds p_nom for deferrable loads
Opened this issue · 2 comments
Describe the bug
At times the optimisation allocates power levels which are above p_nom for deferrable loads.
To Reproduce
Expected behavior
p_deferrable should not exceed p_nom, so in this case it should not exceed 600 W for the 17:00 timesteps.
Then a few minutes later, optimisation is delivering the expected behaviour.

Additional context
deferrable4 (my hot water heat pump) has an additional constraint to complete by sunset, which occurs at the 17:00 timestep.
I suspect the optimisation is allocating additional power to deferrable4 at this point, because it is constrained..
Another set of sub optimal results 5 minutes later:

@GeoDerp , can you assist I think there is a logic error in the stop intervals code that it tries to squeeze in all the power required in the time remaining before the stop interval without consideration of the p_nom restriction.
Hey @purcell-lab , Unfortunately im not verse in that area of the EMHASS code.
Out of curiosity, What happens if 'def_start_penalty': [] in runtime ?
