Don, in as much as you've railed against some of the definitions I used in
trying to explain my understanding of the RPC, I offer the following.

Generators and consumers: Motor windings, (elements of a RPC for example)
consume energy and give it up as torque. Those same windings also generate
energy in the form of counter EMF. In essense current is flowing in 2
directions through the winding. In electronic parlance, you might say there
is both a voltage rise and a voltage fall. I have sense and education
enough to know average current flow in an AC circuit is zero, but you have
tap danced all around the point, by even mentioning it. (Patronizingly,
perhaps)

Aggregate current: That which flows in a network as a result of everything
going on in the network.

Convoluted current: In a manner of speaking, that current which flows in
the load side of a RPC.

BTW much of the definition you question was duly addressed in the little
paper I sent you awhile back. At the time your comments were to the effect
the paper was well researched, well written, etc.
