Inhalt:
This paper discusses the first results using energy value measurements in an SDGS (Smart Distribution Grid System) to control public charging infrastructure in a low voltage distribution grid. Following an extensive simulation test, parts of the local low voltage distribution grid were equipped with basic sensor infrastructure for smart grid system operation. While conventional charging infrastructure is monitored by current and voltage measurements, the chargers were connected to the SDGS using the backend system normally used for billing services. The paper highlights obvious flaws using this technique and introduces possible workarounds. Finally, the first results of the conducted field experience, showing a successful operation cycle are discussed.
