-- 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).
--
-- It works like this:
-- All PR,BA,RE nodes are indexed and tagged with the switching station.
-- The tagging is to allow more stations to be built without allowing a cheat
-- with duplicating power.
-- All the RE nodes are queried for their current EU demand. Those which are off
-- would require no or a small standby EU demand, while those which are on would
-- require more.
-- If the total demand is less than the available power they are all updated with the
-- demand number.
-- If any surplus exists from the PR nodes the batteries will be charged evenly with this.
-- If the total demand requires draw on the batteries they will be discharged evenly.
--
-- If the total demand is more than the available power all RE nodes will be shut down.
-- We have a brown-out situation.
--
-- Hence all the power distribution logic resides in this single node.
--
-- Nodes connected to the network will have one or more of these parameters as meta data:
-- <LV|MV|HV>_EU_supply : Exists for PR and BA node types. This is the EU value supplied by the node. Output
-- <LV|MV|HV>_EU_demand : Exists for RE and BA node types. This is the EU value the node requires to run. Output
-- <LV|MV|HV>_EU_input : Exists for RE and BA node types. This is the actual EU value the network can give the node. Input
--
-- The reason the LV|MV|HV type is prepended toe meta data is because some machine could require several supplies to work.
-- This way the supplies are separated per network.
