The DIgSILENT products PowerFactory and StationWare are used by our customers in complex business processes and use data from other information systems (GIS, SCADA, etc.). In close cooperation with the customer, the DIgSILENT project team develops customer-specific integration solutions that enable centralised and efficient data management and the automation of processes.
Geographic Information Systems (GIS) together with Asset Management Systems are the main sources of network topology and equipment data. Many utilities use GIS exports as a basis for the PowerFactory network model. These exports may comprise detailed substation data including topology, line/cable data, load/generation data and GPS oordinates/schematic diagram information, etc. The built-in Compare & Merge Tool and the versioning mechanism perfectly support the frequent data exchange with GIS. PowerFactory Engines are directly integrated into GIS systems providing calculation functionality such as evaluation of renewable generation connected to the low voltage grid.
The PowerFactory OPC interface is utilised worldwide for real-time integration of PowerFactory with SCADA systems. The applications range from Online State Estimation, simulation mode functions (Dispatcher Load Flow, Contingency Analysis, Switching Validation) to Dispatcher Training Simulator with real-time transient grid simulation. Controller manufacturers use the PowerFactory OPC interface for controller development, e.g. smart grid controllers, PV or wind farm control schemes.
Business Process Automation
PowerFactory supports standard ENTSO-E operation planning processes such as D2CF, DACF and IDCF (Intraday). The Intraday process runs as a fully-automated, parallelised process. The ESB interface adapter features message-based data exchange such as load forecast, planned generator dispatch, day-ahead cross-border exchange programs, UCTE-DEF
files, EMS snapshots, dynamic line rating and market coupling data. The combined MV/LV calculation for the distribution grid of a whole country (>2000 MV substations) has been automated using PowerFactory and bulk data GIS exports.
The PowerFactory Engine Mode provides complete PowerFactory functionality for external systems. The Engines can be controlled via the PowerFactory API and DPL or Python scripts. Various interfaces such as CIM, UCTE-DEF, OPC and DGS support bi-directional data exchange with different systems. The ESB interface adapter connects to an Enterprise Service Bus enabling modern message-based data exchange. The Engine Manager component provides access to multiple PowerFactory Engines via web services. The built-in queuing and scheduling simplifies the Engine integration into other applications.
