Abstract: In this paper the real-life demonstrations for grid control and flexibility intervention based on advanced controllability of flexible resources that were performed at Chalmers University of Technology campus are presented. The demonstration activities were facilitated by the implementation of an IoT platform, which was also used for the visualization and assessment of the results. Through the demonstrations, the successful integration of the required tools to the IoT platform, as well as the efficient employment of the platform for real-life applications have been validated. The evaluation of the results against the defined key performance indicators (KPIs) shows that the coordinated voltage control by solar PVs through model predictive control (MPC) efficiently keeps voltage within the desired limits, while the optimization algorithm for battery energy storage systems (BESs) dispatch for flexibility service (FS) provision, provides financial benefits to the energy cluster that includes the BES, minimizing its energy cost.
