Fuzzy based operation of renewable energy based autonomous micro-grids with hydrogen storage

Electrical supply of remotely located objects - such as telecommunication relay stations, alpine huts, or farms and small settlements in developing countries - requires autonomously operated micro-grids, favorably based on renewable energy sources. Proper design as well as reasonable control of such small scale power systems are posing a challenge which was taken up by the development of a comprehensive counseling software tool which provides for reasonable system design by selection of expedient renewable source(s) as well as short and/or long term energy storage paths; the present paper deals with the setup of optimal operation strategies for the complete plants, based on fuzzy logic.
