# Unofficial ENTSO-E dataset processed by GridKit
|
|
|
|
This dataset was generated based on a map extract from May 25, 2018.
|
|
This is an _unofficial_ extract of the
|
|
[ENTSO-E interactive map](https://www.entsoe.eu/data/map/)
|
|
of the European power system (including to a limited extent North
|
|
Africa and the Middle East). The dataset has been processed by GridKit
|
|
to form complete topological connections. This dataset is neither
|
|
approved nor endorsed by ENTSO-E.
|
|
|
|
This dataset may be inaccurate in several ways, notably:
|
|
|
|
+ Geographical coordinates are transfered from the ENTSO-E map, which
|
|
is known to choose topological clarity over geographical
|
|
accuracy. Hence coordinates will not correspond exactly to reality.
|
|
+ Voltage levels are typically provided as ranges by ENTSO-E, of which
|
|
the lower bound has been reported in this dataset.
|
|
+ Line structure conflicts are resolved by picking the first structure
|
|
in the set
|
|
+ Transformers are _not present_ in the original ENTSO-E dataset,
|
|
their presence has been derived from the different voltages from
|
|
connected lines.
|
|
+ The connection between generators and busses is derived as the
|
|
geographically nearest station at the lowest voltage level. This
|
|
information is again not present in the ENTSO-E dataset.
|
|
|
|
All users are advised to exercise caution in the use of this
|
|
dataset. No liability is taken for inaccuracies.
|
|

|
|
## Contents of dataset
|
|
|
|
This dataset is provided as set of CSV files that describe the ENTSO-E
|
|
network. These files use the comma (`,`) as field separator, single
|
|
newlines (`\n`) as record separator, and single quotes (`'`) as string
|
|
quote characters. The CSV files have headers.
|
|
|
|
Example code for reading the files:
|
|
|
|
# R
|
|
buses <- read.csv("buses.csv", header=TRUE, quote="'")
|
|
# python
|
|
import io, csv
|
|
class dialect(csv.excel):
|
|
quotechar = "'"
|
|
with io.open('buses.csv', 'rb') as handle:
|
|
buses = list(csv.DictReader(handle, dialect))
|
|
|
|
### buses.csv:
|
|
|
|
Describes terminals, vertices, or 'nodes' of the system
|
|
|
|
+ `bus_id`: the unique identifier for the bus
|
|
+ `station_id`: unique identifier of its substation; a station may have multiple buses, which are typically connected by transformers
|
|
+ `voltage`: the operating voltage of this bus
|
|
+ `dc`: boolean ('t' or 'f'), describes whether the bus is a HVDC
|
|
terminal (t) or a regular AC terminal (f)
|
|
+ `symbol`: type of station of this bus.
|
|
+ `under_construction`: boolean ('t' if station is currently under construction,
|
|
'f' otherwise)
|
|
+ `tags`: _hstore_ encoded dictionary of 'extra' properties for this bus
|
|
+ `x`: longitude of its location
|
|
+ `y`: latitude of its location
|
|
|
|
**NOTA BENE**: During the processing of the network, so called
|
|
'synthetic' stations may be inserted on locations where lines are
|
|
apparantly connected. Such synthetic stations can be recognised
|
|
because their symbol is always `joint`.
|
|
|
|
### lines.csv:
|
|
|
|
Buses are connected by AC-lines:
|
|
|
|
+ `line_id`: unique identifier for the line
|
|
+ `bus0`: first of the two connected buses
|
|
+ `bus1`: second of two connected buses
|
|
+ `voltage`: operating voltage of the line (identical to operating voltage of
|
|
the bus)
|
|
+ `circuits`: number of (independent) circuits in this link, each of which
|
|
typically has 3 cables.
|
|
+ `length`: length of line in km
|
|
+ `underground`: boolean, `t` if this is an underground cable, `f` for
|
|
an overhead line
|
|
+ `under_construction`: boolean, `t` for lines that are currently
|
|
under construction
|
|
+ `tags`: _hstore_ encoded dictionary of extra properties for this link
|
|
+ `geometry`: extent of this line in well-known-text format (WGS84)
|
|
|
|
### links.csv:
|
|
|
|
Connections between buses:
|
|
|
|
+ `link_id`: unique identifier for the link
|
|
+ `bus0`: first of the two connected buses
|
|
+ `bus1`: second of two connected buses
|
|
+ `length`: length of line in km
|
|
+ `under_construction`: boolean, `t` for lines that are currently
|
|
under construction
|
|
+ `tags`: _hstore_ encoded dictionary of extra properties for this link
|
|
+ `geometry`: extent of this line in well-known-text format (WGS84)
|
|
|
|
### generators.csv
|
|
|
|
Generators attached to the network.
|
|
|
|
+ `generator_id`: unique identifier for the generator
|
|
+ `bus_id`: the bus to which this generator is connected
|
|
+ `technology`: type of generator
|
|
+ `capacity`: capacity of this generator in MW
|
|
+ `tags`: _hstore_ encoded dictionary of extra attributes
|
|
+ `geometry`: location of generator in well-known text format (WGS84)
|
|
|
|
### transformers.csv
|
|
|
|
A transformer connects buses which operate at distinct voltages. **NOTA BENE**:
|
|
Transformers are _not_ represented in the original dataset, but instead have
|
|
been added at substations to connect AC transmission lines of distinct voltage
|
|
levels.
|
|
|
|
+ `transformer_id`: unique identifier
|
|
+ `bus0`: Bus at lower voltage level
|
|
`bus1`: Bus at higher voltage level
|

### converters.csv
|
|
|
|
Back-to-back converters connecting non-synchronized buses.
|
|
|
|
+ `converter_id`: unique identifier
|
|

|
|
`bus1`: Second bus
