| | | -- SWITCHING STATION |
|---|
| | | -- The switching station is the center of all power distribution on an electric network. |
|---|
| | | -- |
|---|
| | | -- 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. |
|---|
| | | -- 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. |
