Abstract:
In the project “Hybrid-Optimal”, funded by the ministry of environment, climate and energy of the State of Baden-Württemberg, a grid section with a high penetration of renewable energy sources is developed into an energy cell to demonstrate the benefits of the cellular approach in practice. The project partners are Stadtwerke Bühl, Karlsruhe Institute of Technology and SCHMID Energy Systems. The main objectives of the project are to demonstrate that the cellular approach is able to increase the power grid stability and allow the general public to take part in and profit from the energy transition. The core component of the cell is a central hybrid battery consisting of a 5-kW/45-kWh Vanadium Redox Flow Battery, delivered by SCHMID Energy Systems, and an additional 40-kW/56-kWh Lithium-Ion Battery. The operating strategy of the battery system will be optimized periodically regarding current market opportunities. The project commenced in September 2016 and will be completed in December 2018.
