An Autonomous Switching System implemented in the German Demonstrator of GRID4EU

The high share and still massively increasing amount of distributed generation set new challenges to the DSOs in Germany. In order to provide hosting capacity to integrate these resources huge investments in grid infrastructure are required. Moreover, grid operation and grid observation become more complex since power flows become less predictable. Demo1 addressed these challenges with the demonstrator built up in the area of “Reken”, located in North Rhine-Westphalia.

The German Demonstrator of GRID4EU implemented an autonomous switching system that is based on an autonomous interaction between these modules and a lean control centre in the primary substation.
The modules are divided into two groups: Switching Modules and Measuring Modules. Switching Modules can execute the switchgear of their secondary substation whereas Measuring Modules provide measured values. The possibility of autonomous switching provides dynamic topology reconfiguration which is a new concept of operation.
