The resistance and inductive reactance decrease proportional to the number of parallel circuits with small modifications to the inductance due to the different geometry of the parallel circuits.
It is known to be an approximate artistic representation rather than an accurate geographical map. Transformers are not modelled but per unit line series impedances are adjusted to the voltage level. The third version, published in February as Excel spreadsheets has in addition thermal ratings for most transformers and most transmission lines, along with reactive power feed-in, consumption and compensation, so that a full non-linear power flow can be run on the grid.
The map uses OpenStreetMap as a background and Mapbox for displaying the map data. The impedances and limits below are quoted assuming that the system is balanced, so that only positive sequence impedances are given. SciGRID is a project which started in and will be running for three years.
The model contains the impedances and number of circuits of each line, but not the length which can in principle be determined from the impedance and number of circuits, given standard line parameters.
The main European alternating current AC electricity system is operated at 50 Hz. The methodology and validation for the 1st version of the model can be found in the paper Approximate model of European interconnected system as a benchmark system to study effects of cross-border trades ents Zhou and Bialek, There is raster graphic of the US transmission grid at https: This page has been accessed 92, times. In almost all of the world electrical power is transmitted using alternating current with three phases separated by degrees, see Wikipedia: Line capacities were missing.
The node names were obscured so that the model was unusable. It is not totally clear what brid may and may not do with it e.
Power Systems Test Case Archive. The model is intended for a linear load flow only. Optimal Power Flow Cases. This should be the case in the normal operation of the transmission system.
The joint allocation office hosts various official data including PTDFs around the Flow-based market coupling algorithm in use in Europe. The data are not directly available, but rather a registration form is required before obtaining access. The georef-bialek github project is an attempt to fix this; there is also a geo-referenced version from Tue Vissing Jensen.
Interconnected network of Northern Europe
In an unbalanced system, the three phases can be described using the positive- negative- and zero-sequence components, where the impedances are different for each sequence.
On the continent AC transmission fntso are typically kV or kV sometimes quoted as kV, since network operators often run their grid above nominal voltage to reduce network mzp. It is released under a Public Domain Dedication. The PowerWorld file contains spatial data, but in an unknown projection.
Generators are not distinguished by generation source.

GridKit uses spatial and topological analysis to transform map objects from OpenStreetMap into a network model of the electric power system. The 1st version was released in and is no longer available see Archive mirror. The node names are the same as those used by the TSOs. The data is provided as-is without the code that generated it. Line data includes series reactance and resistance, but not line length or capacity or number ents circuits or wires per circuit fntso.
This page was last modified on 17 Novemberat Information, including all geographical coordinates, can be extracted from the web API, but requires further topological processing to be turned into an electrical network model.

The GridKit project provides code for this purpose and has released an unofficial datasetwhich forms an electrical network model complete with buses, links, generators and transformers, full geographic coordinates, as well as all electrical metadata contained in the ENTSO-E map. It contains geo-referenced network nodes and transmission lines at kV and kV.
Views View View source History. The 1st version did not contain the Balkans region. The second version, published in June as Excel spreadsheets, is more useful.
Quoting from the documentation: There is currently no coordinate dataset for the buses. Some power plants may be incorrectly labelled e. Interaction Recent changes Random page. Often it is assumed that the voltage and current magnitudes are the same in each phase, i.
Can model “the main frequency response of the system as well as the main inter-area oscillation modes”. In the table above, the impedances are quoted for a single circuit. The 2nd version of the Bialek European Model is downloadable as an Excel file and in the format of the proprietary modelling software PowerWorld.
In the table the thermal limit for the current is calculated as A per wire at an outside temperature of 20 degrees Celsius. Amprioninteractive map of the grid extension projects. Other networks, such as those for electrified trains, operate at other frequencies and some transmission lines use direct current. Austrian Power Network Grid.
