The research project »INE-VES - Innovative energy storage in networked hybrid photovoltaic systems«, coordinated by the Fraunhofer IEE (formerly Fraunhofer IWES), is concerned with the development and implementation of an intelligent energy management for hybrid systems, i.e. electrically-thermally coupled generator storage systems. Hybrid storage systems have the potential to make a valuable contribution to the optimal grid integration of renewable energies. Innovative storage technologies within the low-voltage grid, smart energy management and superordinated control strategies to build a large virtual storage are being examined.

Within the project it will be scientifically analyzed, how small and distributed electrical energy storages can contribute to a grid integration of distributed generation. Operation strategies for hybrid storage systems are being developed to increase the benefits of storage for the energy grid, as well as for the system operator. These operation strategies will be implemented based on the open source software platform OGEMA as energy management solution, so that the various electricity-heat storage technologies can be optimally controlled in a laboratory test.

New measurement and assessment approaches allow to compare different hybrid storage technologies, and the analysis of the distributed but coupled operation of the various systems.
