One quick question

I tried to model my plant so that it doesn't work during the night, what I have been doing is modifying the dipatch control, and I don't want it working during the night hours,
I've set the turbine out fraction equals to zero.
As soon as I run the simulation, I get the negative values for the power of system generated, what does that mean? please advise.

Hello,

I'm not sure what kind of system you are modeling, but assume it is a CSP system. Those negative values are most likely parasitic electric loads to power to power pumps and heat trace equipment for freeze protection at night.

Best regards,
Paul.
