SciGRID_gas: The merged IGGIN gas transmission network data set

Kurzfassung

Here, this document describes the resulting data set “IGGIN”, where all missing values have been estimated using heuristic processes, and was generated by combining the following data sources: • InternetDaten data set (INET) • Gas Infrastructure Europe data set (GIE) • Gas Storages Europe data set (GSE) • International Gas Union data set (IGU) • Norway data set (NO). The goal of the SciGRID_gas project is twofold: a) to generate a comprehensive gas transmission network dataset for Europe and b) to develop and supply automated processes to create those data sets for Europe. Gas transmission networks and their data are essential for gas network modelling. The modelling community can derive major characteristics from such networks. Such simulations have a large scope of application, for example, they can be used to perform case scenarios, to model the gas consumption, to minimize leakages and to optimize overall gas distribution strategies. The focus of SciGRID_gas will be on the European transmission gas network, but the principal methods will also be applicable to other geographic regions. Data required for such models are the gas facilities, such as compressor stations, LNG terminals, pipelines, etc. One needs to know their locations, in addition to a large range of attributes, such as pipeline diameter and capacity, compressor capacity, configuration, etc. Most of this data is not freely available. However, throughout the SciGRID_gas project it was determined, that data can be grouped into two categories: a) OSM data, and b) non-OSM data. The OSM data consists of geo-referenced facility location data that is stored in the OpenStreetMap (OSM) data base, and is freely available. The OSM data set currently delivers highly accurate topological information on pipelines, however, does rarely contain any additional meta information. The Non-OSM data set can fill some of those pipeline data gaps, and can additionally supply information such as pipeline diameter, compressor capacity and more. Part of the SciGRID_gas project is to mine and collate such data, and combine it with the OSM data set. In addition heuristic tools have been designed to fill data gaps, so that a complete gas network data set can be generated. In this document, the chapter “Introduction” will supply some background information on the SciGRID_gas project, followed by the chapter “Data structure“ that gives a detailed description of the data structure that is being used in the SciGRID_gas project. Chapter “Data sources” describes the INET, GIE, GSE, IGU and NO data sets. To remove any missing data, the chapter “Heuristic methods” describes in detail, how missing attribute values (e.g. pipeline diameter) were generated. This is followed by the chapter “Final data set”, which gives a brief overview on each set of components and in addition summarizes the changes to a previously published SciGIRD_gas data set. The data presented here, e.g. number of pipelines if valid for this current version, but might significantly change with future updates, as additional tools become available, or new relationships between data sets can be made.The appendix contains a glossary, references, location name alterations convention and finishes with the table ofcountry abbreviation.
