For better integration of renewable energies in the distribution intelligent solutions are increasingly in demand. RWE Germany has launched the project "smart operator" to develop "intelligent" solutions in the low voltage network in August 2012.
250 test households in the communities Kisselbach and Wincheringen (Rheinland Pfalz) and Wertachau (Bavaria) are connected to an intelligent low-voltage grid. As a "smart operator" designated control box detects the current condition of the network and optimizes automatically the current flow. It also establishes a communication interface to the test households.
The use of selected, "smart" appliances are aligned by the “smart operator” in a way that as much electricity from renewable sources is used. Caused by the results of this project the expansion of low-voltage systems will be optimised.
