DA as constraint #721

Closed TheOneAndra closed 3 years ago

TheOneAndra commented 3 years ago

DA: Degree of Autonomy TSO: Transmission System Operator EC: Energy Cell

grafik Where: a : the DA E VB : the overall consumed energy E DV : the direct consumption (from the PV panel or from the cell production) E BE : the battery discharge to supply the system’s demand E NB : the energy consumed from the grid

DA = (the overall consumed energy - the energy consumed from the grid) / (the overall consumed energy )

If we simulate with a constraint on the DA representing the inflow TSO --> EC Might be equal to the OEM in the end.

Note that with formula, the system is put under a constraint as a whole. So for now one cannot simulate two energy providers with different minimal_DA. This would be an interesting disctinction for energy cells.

Side note: Would be also very interesting to check the feed-in and outflows between EC and TSO This would be define as a NET ZERO energy constraint: The TSO and the EC can exchange as much as they want as long as the total outflow = total inflow over a given period of time,

(#133)

Hi @TheOneAndra! Can you change this section about the DA according to the new definition, please? This should include a source, range of possible values, meaning of extreme values + intermediary value.
