Hi Paola, In addition to what Dr. Zimmerman said. You can alternatively add the battery voltage to the PV voltage and model it as single source. Example: if PV voltage is 'Vd' and the battery is 'Vb' then V=Vd + Vb Thus, allowing you to model the PV either as Positive or negative injection depending on the bus type model (PV or PQ) to which it will be injected. Hope it may help.
