The power network 1 has a resistive load and therefore the current supplied by the generator 1 to the load is purely resistive.
The power network 2 has a resistive + inductive load and therefore the current supplied by the generator 2 is resistive and reactive.
My question is what does it mean for the generator 2 to supply both resistive and reactive current to its load? Is it a disadvantage for that generator to do so? Are there more losses?
