Reactive Power Definition

[CKent]

Could anyone please direct me to what standard (e.g. IEEE, IEC, etc.) does the reactive power is defined? Better if anyone could give the "exact, word for word" definition of Reactive Power as stated by the any of these standard definitions.

IEEE 100:

(1) (metering) For sinusoidal quantities in a
two-wire circuit, reactive power is the product of the voltage,
the current, and the sine of the phase angle between them.
For nonsinusoidal quantities, it is the sum of all harmonic
components, each determined as above. In a polyphase circuit,
it is the sum of the reactive powers of the individual
phases. See also: magner. (ELM) C12.1-1982s
(2) The product of voltage and out-of-phase component of
alternating current. In a passive network, reactive power represents
the alternating exchange of stored energy (inductive
or capacitive) between two areas. See also: magner.
(PE) [9]
(3) (control of small hydroelectric plants) Power that is in
quadrature with real power, such as used by capacitive or
inductive loads, expressed in kvar.
(PE/EDPG) 1020-1988r
(4) (electrical measurements in power circuits) The square
root of the square of the apparent power S minus the square
of the active power P.
Q = (S^- P^2)^1/2
Reactive power is developed when there are inductive, capacitive,
or nonlinear elements in the system. It does not represent
useful energy that can be extracted from the system
but it can cause increased losses and excessive voltage peaks.
(PE/PSIM) 120-1989r
(5) The vector difference between apparent and real power:
Q = sqrt(S^2- p^2)
