The direction of the energy flow is obtained by the
angular phase shift
φ between voltage and current.
A positive value of the active/reactive power
indicates energy being consumed.
A negative value indicates energy being generated.
E.g.:
P= +10kWh, Q= +5kVAr => Quadrant-1
P= -10kWh, Q= +5kVAr => Quadrant-2
P= -10kWh, Q= -5kVAr => Quadrant-3
P= +10kWh, Q= -5kVAr => Quadrant-4
