Climatic conditions worldwide force the comprehensive integration of renewable and distributed energy resources into the power system, the effective use of the energy and of the existing infrastructures. Business models are changing and becoming more customer-centric: The customers play an active role in energy supply. The way in which the power grid should be managed, as well as the interaction between all actors in the energy value chain, should become more direct, simpler and more structured. INTERACT effectively integrates all innovative technologies of renewable and distributed energy resources in a holistic architecture, and thus designs the first Energy Community worldwide that works in harmony with the power grid.

The used LINK-based holistic architecture unifies all interactions within the power system itself, between the network-, generation- and storage operators, consumers and prosumers, and the market. Through its standardised structure, this architecture facilitates all processes that are necessary for a reliable, economic and environmentally friendly operation of smart power systems in order to establish a beneficial situation for everyone. To achieve this, INTERACT builds on and integrates both success factors: the best practices of the European positive energy districts; and the specific local needs and requirements of the communities. INTERACT crowns with a roadmap that guides the implementation of a Local Energy Community through the description of a general and two specific cases in Sweden and Austria.
