Netze BW, the largest distribution network company for electricity, gas, and water in Baden-Württemberg, Germany’s third-largest state, has launched the largest LoRaWAN deployment in that country.
Working with Kerlink, a solutions provider dedicated to the Internet of Things (IoT), and ZENNER IoT Solutions, a LoRaWAN system integrator and solution provider in Germany, the deployment includes up to 3,000 Kerlink Wirnet LoRaWAN gateways.
“This major deployment in Baden-Württemberg demonstrates the excellent scalability, flexibility, and robustness of LoRaWAN networks…,” said Dr Gerald Troppenz, business development manager ZENNER IoT Solutions.
Flexible grid research
Netze BW is further coordinating the flexQgrid research project which is funded by the German Federal Ministry for Economic Affairs and Energy (BMWi). The aim of the project is to bring the distribution grid, regional power generation, steerable users and market participants such as aggregators together again.
The focus is on the twelve-month field test starting in August 2021, which will involve two medium-voltage and probably three low-voltage networks with flexible consumers such as heat pumps, battery storage units and electric vehicles. If a bottleneck is predicted with simultaneous utilisation of the grids and a ‘yellow phase’ occurs, the traffic light colour ‘red’ must be set by means of approval quotas for generation or consumption systems, thus avoiding intervention by the grid operator.

PSI Software is implementing a quota-based network traffic light model in the research project and will evaluate it together with the project partners with regard to its practicality. For this purpose, a control system field test environment will be connected to the control system of the BW networks in monitoring mode so that the extensions can be tested with real process data without influencing the operating system. In addition, the PSIngo intelligent grid operator software solution will be used to install decentralised network control in the field test environment. The results of the field test will provide valuable information for the further development and integration of the network traffic light model into real network operation.
