Discrete Power vs Three Phase Power?

Hi everyone I am trying to build a drone I have been designing but I am trying to decide on the power system. (Not battery powered)

Although drones aren't my field I am having trouble understanding Discrete Power and Three Phase Power? What are they and what are the differences? Any input is immensely appreciated!

First, describe what "discrete power" is.

How are you planning to get power to the drone?

How much power?

What is the max distance to the drone?

Drones can draw very serious amounts of Current in short peaks.
The Peak-Current is the question that must be addressed first.

The only "3-Phase-Power" is created by the individual Motor-ESCs,
everything else is just plain old DC.

The Drone must be able to deal with the
substantial weight of the Wires that will be supplying it with Power.
This is a big problem.
