Clarity on SAM terms

Hi Paul,
I have been facing issue with understanding the terms 'Parasitic power generation-dependent load' and 'Parasitic power fixed load'. They are given in the SAM simulation results, but there have not been any explanation for these parameters.
Along with that, I am also doubtful whether these parameters are somehow connected to 'Balance of plant parasitic load', 'Auxillary heater boiler parasitic load', and 'adjustment factor'. It would be great if we can get the explanations for these parameters too.
Is there any parameter in SAM which gives us the system pressure in the plant?
Also explain all the terms so that I don't get confused
 

Hi Abhishek,

I assume these questions are about the CSP physical trough model.

"Parasitic power generation-dependent load" accounts for electricity required for parasitic loads that vary with the output of the system, such as for HTF pumps.

"Parasitic power fixed load" accounts for electricity for parasitic loads that are constant.

"Balance of plant parasitic load" and "Auxillary heater boiler parasitic load" are calculated from the inputs at the top of the System Control page.

There is not an output variable called "adjustment factor," but that term is generally associated with the "System Availability" inputs, which for the physical trough model are on the System Control page.

The physical trough model reports the pressure for various parts of the system. There is not an overall system pressure variable.

Best regards,
Paul.
