Comparison between accumulated

[Syndicate_Admin]

Hello everyone, and thanks in advance.

I have modeled a photovoltaic plant.

For the surplus energy that it exports to the grid, the company pays an amount, which I calculate with a measure: "Valor_exportación", reducing it from the payment for imported energy in deficit hours "Valor_importación", with the payment for the surplus limited to the value of what was imported in the monthly calculation. The model is calculated hour by hour with a hierarchy of DateTime Year-Month-Day. I need a measure that adds, for the selected period, the net value of the energy exported (Valor_exportación limited in the monthly calculation to the Valor_importación)

Can anyone help me?

Thanks a lot
