Development and simulation of an efficient small scale interactive combined wind/photovoltaic/fuel cell power system

In this paper, development and simulation of an efficient small-scale hybrid wind/photovoltaic/fuel cell for supplying power are presented. The hybrid system consists of wind and photovoltaic as a primary power system. The solar and wind energy are complementary to each other. The solar energy has always be interrupted during the night. .During the day the sun is strong. The wind is more at night. In summer sunshine is good and wind is weak. Spring and winter has more windy day, so they are complement. The objective of this study is to design and control a hybrid system that guarantees the energy continuity. A simple control method is applied to the proposed configuration to simultaneously achieve three desired goals: to extract maximum power from each hybrid power system component; to guarantee dc bus voltage regulation at the input of the inverter; to reduce the harmonic distortion. The power fluctuation of the proposed hybrid system has been reduced as compared to that of each individual system and it has been completely suppressed using the FC system.
