Power Tower with Molten Salt Storage controlled output

Hello,

I'm trying to have the power plant put out a very controlled amount of electrical energy. I don't want it to utilize the resource to its' maximum potential, I'm not using dispatch optimization, I'm trying to match a load almost exactly using 9 operating modes based on the load. When trying to do this if my Storage isn't large enough and the capacity of it maxes out then for some reason the heat goes directly to the power block and it outputs the maximum it possibly can, causing complete haywire for my desired case-study. Is there a way to STOP this from happening and have the power block follow my instructions exactly without having to unrealistically raise the size of the storage?

Hello,

SAM's CSP models aren't designed to match a specific load. They do their best to supply sufficient heat to the power cycle for it to operate at its nameplate capacity. When the TES is full, and energy is available from the solar field, the model will deliver that energy to the power cycle. If there is more field energy than the power cycle needs to operate at nameplate capacity, it attempts to reduce the field energy by defocusing the heliostats.

You might try adjusting the turbine output fraction for periods when the power cycle's electrical output is higher than you want it to be.

Best regards,
Paul.
