Fuzzy Logic Based Management of A Stand-Alone Hybrid Generator
Publication Type
Conference Paper

The paper deals with a fuzzy logic based strategy
managing the power flows in an hybrid generation plant.
Such a plant works in island mode and is composed of: a
wind turbine, a photovoltaic generator and a fuel
cell/electrolyzer energy storage system. The performances
of the proposed strategy are evaluated by simulation in
different operating conditions. To this purpose some
performance indexes are considered, such as: the frequency
deviation, the stability of the DC bus voltage and the AC
voltage total harmonic distortion. Simulation results
confirm the effectiveness of the proposed power
management strategy, providing the ground for the
practical realization of a fuzzy logic based control system.
Moreover the efficiency of the developed fuzzy logic
controller is compared to that of a more conventional
controller taking into the fuel cell H2 consumption, the
amount of H2 generated from the Electrolyzer and the final
battery state of charge (SOC).
