54 Introduction to Electrical Power and Power Electronics
As the load current decreases from 900 to 600 A, we note that the battery
bus voltage rises from 120 to 130 V, as expected.
These answers can also be derived graphically in one step by plotting the Battery-2
line backward starting from the right-hand side and drooping as we increase its
load current from 0 to 600 A toward the left-hand side. This is left as an exercise.

The load sharing can be adjusted by raising or lowering the voltage droop line of one or
both sources working in parallel. This is generally done by changing the no-load voltage,
which, in turn, raises or lowers the terminal voltage versus load line while maintaining
the droop rate. In transfor
