Grid exchange formats

This section is dedicated to the description of the various grid formats available in PowSyBl. While IIDM is at the core of it, it is possible to import and/or export data in a number of formats that may be dedicated to European data exchanges or network simulation via different tools: check them out below.

Data format	description	import	export
CIM-CGMES	the standard format for European grid data exchange	✔	✔
UCTE-DEF	the legacy format for European grid data exchange	✔	✘*
IIDM (XIIDM, JIIDM, BIIDM)	the internal data model of PowSyBl in a XML / JSON / binary format	✔	✔
IEEE-CDF	a IEEE standard format	✔	✘
PSS®E	the format for power flow analysis on Siemens PSS®E software	✔	✘*
PowerFactory	the format for DIgSILENT PowerFactory software	✔	✘
Matpower	the format for the free and open-source Matlab toolbox dedicated to power system simulation and optimization	✔	✘
AMPL	a data separated value format easy to parse with AMPL	✘	✔

* Note that updated export is available, that is, export is possible if the file was imported with the same format. For instance, if you import a UCTE-DEF file in powsybl, you can update some elements and then export it back to UCTE-DEF format, but you cannot export to UCTE-DEF format a file imported from another format.
