In short, yes, to everything you are trying to do.
I would personally put 2 generators at each bus (2 rows in the gen table with
the same bus number), one for the distributed generation and the other to
represent the dispatchable portio of the load. I’d combine the fixed portion of
the load and the fixed injection from the solar PV (assuming it is not
curtailable) into a net load number to put in the PD, QD columns of the bus
matrix. No need to use the load2disp() function at all unless you find it
useful just to initially create the entries in the gen and gencost matrices for
you.
