In this paper, a detailed modeling and simulation of
solar cell/ wind turbine/ fuel cell hybrid power system is
developed using a novel topology to complement each other
and to alleviate the effects of environmental variations.
Comparing with the other sources , the renewable energy is
inexhaustible and has non-pollution characteristics. The solar
energy, wind power, hydraulic power and tidal energy are
natural resources of the interest to generate electrical power.
As the wind turbine output power varies with the wind speed
and the solar cell output power varies with both the ambient
temperature and radiation, a fuel cell with ultra capacitor bank
can be integrated to ensure that the system performs under all
conditions. Excess wind and solar energies when available are
converted to hydrogen using electrolysis for later use in the
fuel cell. In this paper dynamic modeling of various
components of this isolated system system is presented.
Transient responses of the system to step change in the load,
ambient temperature, radiation, and wind speed in a number of
possible situations are studied.
Modeling and simulations are conducted using
MATLAB/Simulink software packages to verify the
effectiveness of the proposed system. The results show that the
proposed hybrid power system can tolerate the rapid change in
natural conditions and suppress the effects of these
fluctuations on the voltage within the acceptable range.The
proposed system can be used for off grid power generation in
non interconnected areas or remote isolated communities of
nation.
