The 1st version was released in and is no longer available see Archive mirror. 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.

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 by Zhou and Bialek, ejtso This has several advantages: Views View View source History.
On the continent AC transmission voltages are typically kV or kV sometimes quoted as kV, since network operators often run their grid above nominal voltage to etso network losses. The model is intended for a linear load flow only. The map uses OpenStreetMap as a background and Mapbox for displaying the map data. The 2nd version of the Bialek European Model f downloadable as an Excel file and in the format of the proprietary modelling software PowerWorld.
Only cross-border lines are assigned thermal capacities. The map includes information on the number of circuits and the voltage levels of transmission lines. GridKit uses spatial and topological analysis to transform map objects from OpenStreetMap into a network model of the electric power system. Similarly the capacitance increases proportional to the number of parallel circuits again, roughly because of changing geometry.
entsi Power-carrying capability can be increased by having several circuits on a single pylon, so that wire bundles always appear in multiples of 3 in power lines. This should be the case in the normal operation of the transmission system. The second version, published in June as Excel spreadsheets, is more useful.
Line capacities were missing. Other networks, such as those for electrified trains, operate at other frequencies and some transmission lines use direct current. The georef-bialek github project is an attempt to fix this; there is also a geo-referenced version from Tue Vissing Jensen.

In etso table the thermal limit for the current is calculated as A per wire at an outside temperature of 20 degrees Celsius. Quoting from the documentation: In the table above, the impedances are quoted for a single circuit. The impedances and limits below are quoted assuming that the system is balanced, so that only positive sequence impedances are given. Can model “the main frequency response of the system as well as the main inter-area oscillation modes”.
The abstraction and all additional modules are controlled by a Python-environment.
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. 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. This page was last modified on 17 Novemberat The data are not directly available, but rather a registration form is required before obtaining access.
The model covers voltages from kV a single line in the Balkans up to kV. It contains geo-referenced network nodes and transmission lines at kV and kV. 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.

It is not totally clear what one enyso and may not do with it e. Python for Power System Analysis. The node names were obscured so that the model was unusable.
