Hi all , i am working with an optimization for minimize the cost of hydrogen production and maximize the usage of renewable energy to produce hysrogen, the renewable energy is not availbe for all days , there is some days i have to import power ?

Hi all , i am working with an optimization for minimize the cost of hydrogen production and maximize the usage of renewable energy to produce hydrogen, the renewable energy is not available for all days , there is some days i have to import power from the grid , my question regarding this imported power ,how can i put it in the optimization because i have other inputs as a vector(from 1 to 365 days), is it one value with one price or i have to put it as a vector with his price (from 1-365 ) and then optimization will choose between them.
