The EIT DIGITAL Innovation Days event gave research groups and startups the occasion to present their solutions to an interested audience out of politics, business and science. The demonstrator was part of the booth in which the SDSO partners, represented in Berlin by associates of DFKI, TU Berlin, Cefriel, Engineering and Easy Smart Grid, presented the results of the SDSO project. The Demonstrator simulates a micro grid with four water pumps as flexible consumers using renewable energy. Each pump is controlled by a low-cost SDSO controller that follows a single price signal, continuously formed out of the total balance of renewable energy supply and consumption. The demonstrator was a big attraction in Berlin, and even visitors from science, industry and finance showed a lot of interest in the technology and shared their visitors’ cards for further contacts.
