The diagram below sums up the signs of the power as a function of the
phase angle between V and I:
Quadrant 1: Active power P
sign + (power consumed)
Quadrant 2: Active power P
sign - (power generated)
Quadrant 3: Active power P
sign - (power generated)
Quadrant 4: Active power P
sign + (power consumed)
