Are you saying the concept is meaningless?
Or do you think you provided a definition?

"Standing wave power" is an oxymoron. There is simply
zero power in standing waves. The dot product of the
net voltage and net current in an ideal standing wave
is always ZERO.

Power (watts) is the measure of energy (joules) passing
a measuring point in one second. One can measure the
forward power. One can measure the reflected power. One
cannot measure any standing wave power because it is
always equal to (Pfor - Pref) which for ideal standing
waves is *always* zero.

If the net energy flow is zero, as it is in ideal standing
waves, the power is zero, by definition, because zero net
joules are flowing. And, sure enough, the standing wave
voltages phasors are *always* 90 degrees away from the
standing wave current phasors and they are not moving left
or right. They are rotating around a fixed spacial point
on the wire.

Standing waves are a very sophisticated illusion.
