Negative power is a fallout of the math model being used.
For instance, V*I*cos(theta) is negative when theta=180 degrees.
theta=180 degrees for reflected power.

If you have a windmill generator connected to your house
power wiring, you can cause your watthour meter to run
backwards. By convention, that would be negative energy
consumption.
