In their own words
DIgSILENT PowerFactory
DIgSILENT PowerFactory is software for analyzing electrical generation, transmission, distribution and industrial power systems. Its study areas include renewable integration, distributed generation, and medium- and low-voltage networks. Available analyses cover load flow, short circuits, contingencies, protection, stability and electromagnetic transients. Users can automate work with Python, DIgSILENT Programming Language, a C++ API or a parallel task automation tool. The base package imports and converts network data; its DGS interface exchanges data in ASCII, XML, CSV and ODBC formats for GIS and SCADA connections. Additional interfaces include OPC DA/UA, IEEE C37.118 simulation and FMI 2.0 co-simulation, though some require separate licences. Editions range from a local SQLite setup to licence-server management and shared project data using Oracle, SQL Server or PostgreSQL. The 28-day demo is free for one user, with predefined functions, and excludes DGS, exports and API. Commercial pricing is available on request; platforms listed are Windows, API and self-hosted.
