I am working on a mathematical optimization model for a fuel cell.

Currently I am facing a problem with the ramp-up of the cell.

I have a modulation ramp of 4% of the nominal power (58.3 kW) per minute.

My constraint in the model has to be in kWh (I have to precise that my model is a hourly simulation during one year).

Concerning the conversion of the power in other constraints (as for FC capacity constraint) I simply multiplied the power times one hour and I should get the energy in kWh.

But for the ramp-up constraint I am really struggling with the conversion.

Anyone that has an idea how to obtain it?

Thanks in advance for any help.
