HELP DESIGN 2 PLANT CSP was created by yfritzc

I am developing two cases of solar tower central simulation with molten salts. The first case is to design the entire plant and the second case is to design two smaller plants that meet the total energy requirement. When I design the smallest plant, it gives me higher tower values and number of heliostats. Help I don't understand why this happens. Im put the same MS and the same full load of storage. Honestly i no have idea if this is the problem. HELP

Dear Yasna,

Can you send me a copy of the .sam file or files that show these results?

Best regards,
Paul.

Thank you for sending the files.

In the attached file, I imported the Option b and Option c cases into the Option A file so that it is easier to compare the different cases. Note that I changed the weather file to Daggett, California. You should change it back to your weather file.

Please use the "Inputs browser" on the File menu to see a list of inputs that have different values in the three cases. You can see that in addition to a different nominal capacity (design turbine gross output), there are other parameters that are different such as the solar multiple, receiver dimensions, etc. You can change the input variable values in the inputs browser table to make the cases more consistent.

Also, after you change the input parameters, be sure to generate a new heliostat layout and optimize the layout for each case to see what the resulting tower height and number of heliostats is.

Best regards,
Paul.

If my 9100 MW consumption plant has 10 hours of storage, the 4550 should be half the time?
The solar multiple would change for each one?

The solar multiple is an input. You will have to determine the optimal value of the solar multiple that results in a solar field that can both drive the power cycle and meet the storage requirements.

Best regards,
Paul.
