Prof. Antonello Monti was awarded the 2022 Innovation Award of the State of North Rhine-Westphalia for his research on the IoT platform SOGNO (Service Oriented Grid for the Network of the Future). The SOGNO software platform provides distribution grid operators with improved control, through which better usability and optimization of energy sources are to be achieved. 

Innovation Minister Prof. Dr. Andreas Pinkwart emphasized: "Business and society have set themselves ambitious goals: By 2045, we want to have a climate-neutral economy in North Rhine-Westphalia. To ensure that this transformation succeeds, we are shifting towards a more sustainable energy supply based on renewables. This poses huge challenges for electricity distribution networks. Prof. Monti and his team have developed a platform to make better use of the capacities of existing grids thus supporting the expansion of renewables. Such innovative solutions can facilitate Germany's energy transition and boost acceptance among citizens."

ACS has been serving as Technical Manager of the H2020 project SOGNO from 2018 to 2020. In the framework of this project, a new architecture for service-oriented network automation has been developed and tested in real grids in 3 different test sites. The results of the project influenced further research projects such as the H2020 Platone, coordinated by Prof. Monti, where the platform is further developed and tested in 3 field tests in Germany, Greece and Italy. At the same time the ACS group thought it made sense to create the conditions for a long term sustainability of the project. For this reason, Prof. Monti together with Dr. Mirz, proposed the SOGNO architecture as project in the Linux Foundation Energy. The Foundation recently accepted the project making the work of ACS a candidate to become a de-facto worldwide standard.

This success got the attention of the press as shown by a recent paper in Forbes mentioning the research in ACS as key innovation for the grid of the future.
