full load hours of TES was created by oukili.mohamed

hello all,

what does it mean Full Load Hours of TES???

what I understand, it's time in hours of thermal energy storage before transmitting to power block !!!!

I want an explanation of that. and thanks.

The input variables, including Full Load Hours of TES, are described in SAM's Help system.

Full Load Hours of TES is the thermal storage capacity expressed in hours of power block capacity. For example, for a parabolic trough system with a 100 MWe power block and 6 hours of storage, the TES capacity would be 100 MWe x 6 hours = 600 MWhe. For a power block with a 0.37 cycle conversion efficiency, the equivalent thermal capacity would be 600 MWe / 0.37 = 1,621 MWht.

Best regards,
Paul.

Thank you for the explanation.
other things, in the case of The physical trough model, SAM uses fossil energy to produce electricity???

and thank you very much.

For both of SAM's trough model, you can include a fossil backup system that provides supplementary heat to the HTF to maintain design temperatures. The trough models do not model hybrid power systems where the turbine can be driven either by solar energy or natural gas.
