After deactivating the other power plants and enabling the storage system, the model generates the following data.
However, I do not fully understand how to interpret the BATTPWR output variable. Does BATTPWR represent the amount of electricity discharged from the storage system at different points within the model’s time slices in order to contribute to meeting the electricity demand?
Also, how should BATTPWR be interpreted in relation to the PWRSOL and PWRDIST variables?
Dear @Mario, you are right. BATTPWR represents the combined charger-inverter system, and its output is equivalent to the amount of electricity discharged by the battery.
I’m not sure which system configuration you are representing, but if you only have BATTPWR, PWRSOL, and PWRDIST, the battery is charged by the solar power plant during the daytime timeslices and then discharged during the night timeslices to meet the corresponding demand.
The electricity produced by either the solar power plant or the battery is represented by ELC001, which would normally feed into the transmission system (PWRTRN) and be converted to ELC002. This, in turn, feeds into the distribution system (PWRDIST) and becomes ELC003, which represents the final electricity demand when the power system is the only system being modelled.
In your case, it looks like the transmission system is not being considered. Therefore, the link is direct between the solar power plant and the battery on one side and the distribution system on the other, essentially representing a mini-grid.
