PowSyBl provides a complete internal model of the electrical grid, complete with substations, voltage levels, AC and DC lines, two- and three- winding transformers, batteries, generators, loads, shunt and static VAR compensators, and other related equipment.
For security analyses, PowSyBl enables users to define contingencies on the network. The grid model can also be enhanced with extensions that provide complete equipment modeling, including dynamic profile, short-circuit profile, and monitoring.
PowSyBl also provides importers and exporters for several common pan-European exchange formats – ENTSO-E CIM/CGMES, UCTE-DEF, and more.
PowSyBl as a library provides several APIs for power system simulation and analysis, including power flow computation, security analysis, remedial action simulation, sensitivity analysis, time domain simulation, and other simulations. These simulations can run either on a personal computer or on a server. The separation of the simulation API from the implementations allows developers to provide their own implementations if necessary, making the framework very flexible.
PowSyBl is also available as a command line tool for quick-shot modelling and simulation. PowSyBl scripts may be written and executed thanks to the dedicated Domain Specific Language (DSL) code included in the project.
All features of PowSyBl are exposed as web services to make it easy to build web-based applications on top of the framework.
PowSyBl includes many features:
- Grid data model, described with Java classes
- Extension capability with plugins
- Data management system
- Importers and exporters for several formats (CIM-CGMES, UCTE, and others)
- APIs to various computation modules (load-flow, security analysis, short-circuit computation, sensitivity computation, optimizers, AMPL)
- Distribution framework for HPC (tested on a 10,000-core platform)
- Advanced functions: grid model merging, remedial actions manager
- Modular architecture based on plugins
PowSyBl as a library provides several APIs for power system simulations and analyses, including:
- Power flow computations
- Security analyses
- Remedial action simulations
- Short circuits computations
- Sensitivity computations
- Time domain simulations
These simulations can run on a supercomputer – this has been tested using the CORDIS iTesla project with the Curie supercomputer.
PowSyBl was initiated by RTE and contributed to LF Energy in 2019.
