PSS/E picks current injection of bus to solve the equation. So either CURNT(Modeled as other types) or ISORCE(Modeled as Generator) array need to be taken care by your own. Please note that those arrays are both complex type. There is an example available in POM. Please refer "Writing a Basic Load Model" chapter. The ISORCE is similar with CRUNT, however, you also need consider ZSORCE affection.

I calculated Ud and Uq and I plan to use ISORCE:ISORCE(MC)=VDIP/ZSORCE(MC)*MBASE(MC)/SBASE. VDIP is complex type. But I don't know how to transfer Ud and Uq into VDIP. Besides, in PAGV2, it shows that ISOURCE = (iq - jid) source × (cosδ + j sinδ). What does δ stand for, and how to get it? Thanks.
