Spurring a Clean Energy Revolution in Germany With Grid-optimized Charging
Electric vehicle (EV) adoption is increasing fast in Germany, the fourth largest auto market in the world. If EV charging loads on a specific feeder grow faster than anticipated, the distribution transformer that serves that load can quickly become overloaded. As a result, industry participants are eager to implement grid optimized charging. There are pioneering research and joint projects involving utilities and IT service providers to take on this challenge. One example is a low voltage monitoring project from MITNETZ STROM, the largest regional distribution system operator (DSO) in eastern Germany, and Robotron, a leading provider of software for connectivity and condition monitoring in cooperation with Moxa. Their goal: to get visibility into feeders and EV penetration trends.
The project sought to improve transparency for low voltage monitoring due to increasing EV charging demands.
Previously, the distribution system operator (DSO) could not monitor daily behavior of single feeder lines, which meant that the company lacked reference data and faced challenges in identifying necessary component upgrades.
Equipping each station with monitoring hardware and software would cost millions. The operator needed a cost efficient method of recording all relevant measured variables to guarantee network stability.
Robotron and Moxa are IIoT partners. They provide a joint solution with out of the box cloud connectivity.
Robotron uses Azure IoT Hub to ingest sensor data collected by a Moxa gateway and processed by Robotron's RoboGate software at the edge. A dashboard provides easy to interpret charts for the last 8 and last 72 hours.
Moxa's IIoT gateways enable zero touch provisioning, ensuring that authorized devices are connected to the correct system, simplifying integration and device deployment.
The DSO now has the information they need to improve maintenance and operational efficiency.
The solutions can be rolled out easily to other parts of the company's grid. Robotron is expanding the deployment to 65 sites, which will provide another 600,000 data points.
Viva la green revolution! The future of energy management is taking shape in Germany.
