Operational modes of hydrogen energy storage in a micro grid system

The proposed operating modes for hydrogen production from renewable energy sources are presented in this work. The designed system is put together to support the investigation of energy requirements in a preliminary focus on residential application. The sensory components of the controller observe, in real time, the incoming energy changes and compare it with the system demand and level of stored energy. The controller output command selects the most economical and energy efficient mode for effective dispatchable system operation. Instantaneous short term requirements of power are exchanged with the hosting grid to mitigate instantaneous intermittency. The modular concept of the built infrastructure enables researchers to test different modes of operation such as a micro grid functionality under various energy supply and load demands. Moreover, the system is designed for use as a testing facility of hydrogen generating units as well as newly designed fuel cells.
