The aim of cFlex is to tap unused flexibilities in cellular organized prosumer communities as a collective system(-network) or as services to enable increased use of renewable energy sources in the distribution network and to coordinate production, storage, and consumption over long periods and regions. For this purpose, the cooperative bundling of different prosumers, network segments, and regions within (regional) Local Energy Communities (R / LECs) aims to optimize the overall state of the energy grid. By applying a cellular control approach including data-based analysis as well as neural forecasting models balancing mechanisms between energy supply and demand can be activated automatically at different network levels.

The Department of Integrated Sensor Systems contributes expertise in distributed control systems. The main tasks are the development of use cases, the definition of interfaces and the implementation of control concepts to optimize the energy flow in energy communities for the benefit of its participants and to support the power grid to avoid supply bottlenecks on the local level. Recently, the department published a technical framework on Local Energy Communities at IES to provide standardization.

** The project cFlex is partially co-funded by FFG and Klima- und Energiefond within the 5. Call 2018 of the program Energy Research (e!MISSION), Energy Research.
