Expertise related to the project

FREQCON is a leading German engineering and manufacturing company of power converters and control systems for renewable energy systems and energy storage applications. The core task of FREQCON in the project is the implementation of control strategies for virtual inertia in industrial scale energy storage infrastructure. FREQCON is already active as a system integrator on the European market and therefore has great knowledge about requirements of storage systems for different applications and knows their integration potentials. Moreover, FREQCON is already selling power electronics such as inverters for storage system. The HyFlow concept offers an optimal basis for the continuation of these activities within more complex energy systems with the possibility to deliver even the fastest grid services e.g. virtual inertia to connected grid sections. FREQCON works as a system integrator to build up the industry-scale demonstrator of the hybrid energy storage system developed during HyFlow.
