Enabling e-mobility | Grid connection issues

Stadtwerke Fellbach (SWF) is actively tackling the challenges of the energy transition. In addition to operating a large number of its own PV and CHP plants, this also includes expanding the grid. For years, the company has been increasing cable cross-sections and equipping transformer stations with 630 kVA transformers in order to cope with the increasing dynamics in the grid due to new consumers such as electric vehicles and heat pumps as well as feed-in from PV systems. In addition, SWF already operates 5 public AC charging points in the city, but is planning to significantly expand the charging infrastructure in 2022. As part of the KfW subsidy for private wallboxes, which has now ended, there has been a significant increase in grid connection issues in Fellbach. It was a challenge to process these optimally and take the new consumers into account for grid planning.

Measurement data show
uneven capacity utilization

The grid operator therefore started looking for a solution to obtain data from the low voltage and opted for SMIGHT Grid. After just a few weeks, Fellbach was able to see which transformers were already breaking thresholds and was able to reduce loads through targeted switching. The identification of unbalanced loads also made it possible to better distribute the load in the grid.

We need more brains instead of more excavators to better understand our grid and prepare for the future. More brains are only possible with digital solutions – like SMIGHT Grid. With SMIGHT Grid, we can see what is happening in our grid and respond appropriately.

Outlook& Conclusion

Logo Stadtwerke Fellbach

Now that Fellbach has created the basis for digitalization in the network by using the SMIGHT solution, further projects are being tackled quickly. For example, the company is currently working on a process to identify suitable locations for public charging stations. There is also a particular focus on documenting the charging infrastructure that has been installed and all feeders. Network operation can only work if all “players” in the network are known and visible. The ideal solution would be an intelligent cable distribution cabinet that communicates with all wallboxes in the cable harness, optimally distributes the power and thus makes perfect use of the cables.
