COMPARATIVE STUDY OF MAXIMUM POWER POINT IN BOTH FULL SUN RAYS AND CLOUDY WEATHER CONDITION BY MATLAB SIMULATION

Abstract

Renewable energy is the alternative source of energy
corresponds to the conventional energies to mitigate the
power demand for large population in the world. Fuels
available in the world are constant. After a few decades it
will be unavailable for mitigating the large demand. On
the other hand conventional energy is much more
harmful for polluting the environment. So the world is
concern with on alternative energy sources which are
nonconventional energy such as wind energy, geothermal
energy, tidal energy, hydro energy and solar energy. All
of indicated sources of energies are more environmental
friendly and infinite. However, this paper deals with the
solar energy. In previous study, latest information on
about solar energy conversion efficiency is only about
16%. So if it is possible to increase this efficiency to as
high as possible then it will be more expected to all. For
this reason the focus on this paper is to extract maximum
power from the solar panel in different temperature
condition. Here PV system is modeled and simulate to
track maximum power point available from the system.
This research work has been carried out with the
modeling of solar panel and makes its approximation in
both full sun rays and partial cloudy weather condition
and simulate it using MATLAB coding. Finally the
outcome of this work is mostly satisfactory and
encouraging.
