IoT Integration for Combined Energy Systems at the CoSES Laboratory

Abstract

Combined Smart Energy Systems (CoSES) microgrid lab at TU Munich has a large number of measured and calculated data points which need a robust tool to monitor and visualize. Furthermore, the tool should be simple to use among microgrid researchers from different fields of study. Based on these requirements, an IoT dashboard using open-source tools for experiment monitoring and visualization is developed for the CoSES microgrid lab. The solution uses InfluxDB 2.0 as a time-series database and Grafana for the visualizations. The dashboard can be easily customized and is both locally and remotely accessible from any modern browser. This enables the researcher to analyze the experiment data without detailed knowledge of the Power hardware-in-the-loop setup. A demonstrative experiment is conducted using one CoSES prosumer to verify the toolchain and the results are shown in the paper.
