-- SWITCHING STATION
-- The switching station is the center of all power distribution on an electric network.
--- The station will collect all produced power from producers (PR) and batteries (BA)
--- and distribute it to receivers (RE) and depleted batteries (BA).

+-- The station collects power from sources (PR), distributes it to sinks (RE),
+-- and uses the excess/shortfall to charge and discharge batteries (BA).

+-- For now, all supply and demand values are expressed in kW.

-- It works like this:
-- All PR,BA,RE nodes are indexed and tagged with the switching station.
