• DIgSILENT PowerFactory is one of many powerful tools for performing power system analysis

• Needed for detailed distribution and transmission planning• Data accuracy and integration with other systems (e.g. GIS) essential• Complexity increases in high‐renewable power systems, increasing the need for 

modelling• Investigation through:

• steady‐state analysis (load flow, short‐circuit analysis, protection, contingency analysis, time‐series analysis)

• dynamic/transient analysis (RMS, EMT)

• PowerFactory offers many specific tools to help power system operators in their analysis
