The significance of photovoltaic hybrid systems with fuel cell co-generation and supercapacitor short-time energy storage is discussed. The benefits of a fuel cell-supercapacitor hybrid unit, namely increase of energy efficiency and fuel cell lifetime, are pointed out A 1,2kW experimental system developed for testing of new predictive and optimizing energy management algorithms is presented. New classification based models for the forecasting of fluctuating photovoltaic and load time series are briefly discussed.
