JuPilot
In the LLEC::JuPilot project, a modern, sector-coupled energy system is designed, installed and operated. For this purpose, energy users (new building of the JuLab student laboratory), regenerative generation units (photovoltaics, small wind turbine) and short- or long-term storage components (lithium-ion battery, hydrogen storage) are interconnected with the help of information and communication technologies. A cloud-based, holistic control system is to ensure the optimal operation of this system. On the one hand, JuPilot serves as a mini-real laboratory, e.g. for the development and validation of new control algorithms including energy use. On the other hand, it enables conclusions to be drawn about the optimal operation of the entire LLEC campus in terms of energy technology.
