Fledge could be used for many use-cases.

Other use-case idea's include:

• 61850 gateway between the substation and the central systems

South/North plugin: 61850

Concept: IEC61850-90-2

• 61850 to 104 gateway between the substation and the central systems

North: 104

South: 61850

Concept: IEC61850-90-2 / IEC61850-80-1

• Local validation of 61850 measurements (e.g. kirchhoff law)

South: IEC61850

• DER agent

North: 61850

South: depends on the connect hardware

Concept of scheduling LN: IEC61850-90-7 (figure 13)

Example specification: Netbeheer Nederland

• DER agent controller

North: unkown

South: 61850

Controller to control a DER agent

• Part of software defined substation / centralised control and protection

North: 104/61850

South: not known yet

• Local configuration collection and storage (what configs are running in the substation)

North/south: yet unknown, depends on the vendor

• Test local configurations

South: 61850

• Collect and redispatch fault recordings

Collect COMTRADE files from IED's
South: COMTRADE / PQDIFF

North: unkown

• Ad-hoc fault recording control

South: probably IEC61850

• Local grid safety analyzer

Determine locally if the grid is running in a safe condition.

South: 61850
