Abstract
This paper represents a versatile simulation process
of a photovoltaic module with buck-boost converter mainly using
matlab function in simulink platform. All the mathematical
equations associated with the simulation of photovoltaic module
and buck-boost converter is described with best clarity. The
obtained simulation results from this model are investigated to
analyze the performance. This model can also be used for the
simulation of any specified PV module and converter with least
changing in parameters.
INTRODUCTION
To overcome the challenge of energy for the world needs from
the last few decades a lot of research is going on renewable
energy among them solar energy is the pioneer, at present a lot
of research is going on this area. sun is the constant unique
source of energy as long as the world live, the sun will
continue to give its energy to the earth. Unfortunately, a very
little amount from the huge energy which sun gives to earth
can be utilized. The amount of energy comes from the sun is
nearly 12.2 trillion watt-hours per square mile per hour [13]
and really it’s difficult to believe that the world’s rate of
energy consumption is only 0.1% of this gigantic amount.
On the other hand, due to the depletion of the energy source
like coal, oil and natural gas with the rapid growth of
population and dramatic industrialization a long term solution
of energy crisis has become inevitable. That’s why most of the
research at this moment is going on how more energy can be
captured from the sun.[3][15]
CONCLUSIONS
This model represents a versatile and simple way of
photovoltaic module simulation with a buck-boost converter.
The characteristics curves obtain from this model is matched
with the theoretical result which ensures the validity of this
model. This model can also be used as a fundamental stage
for further extension and future work like partial shading
effect analysis, converter connection for supplying load in
standalone PV system, high voltage PV application, smart grid
photovoltaic interconnection system .
